[android-developers] Re: Why different icon sizes?

[Nobu Games]

Yes, this is how the system works for drawables. Here a quote from the 
Android documentation:

The system handles most of the work to render your application properly on 
> each screen configuration by scaling layouts to fit the screen size/density 
> and *scaling bitmap drawables for the screen density, as appropriate*.
>

(Source: 
http://developer.android.com/guide/practices/screens_support.html#support)

The only real problems arise when:

   1. Your only drawable available has a too low resolution. Upscaling on a 
   high density screen will make it look slightly blurry. That is especially 
   noticeable when your app icon is right next to a hi-res icon.
   2. The Android system's scaling introduces unwanted artifacts. By 
   providing your own set of icons you have full control over the appearance. 
   This is especially an issue with 9-patch drawables, since the slice markers 
   may bleed into the image area due to interpolation and the markers 
   themselves may not be "readable" anymore for slicing up the image. So 
   especially in case of 9-patch drawables you probably want to provide 
   different versions for each supported screen density.

[android-developers] Re: About Application promotion

[Nobu Games]

I guess key in 3) is "without informed user action". In your scenario 
tapping a banner ad is a user action. What appears to me as legal grey area 
is the "informed user" bit. How can we possibly know that the user is 
"informed" and does in fact know that they are clicking a banner ad for an 
app, that will open its Google Play store page for installation? That 
phrase implies that the user is supposed to be knowing what they are doing. 
What this Google Play policy probably tries to express is that the banner 
ad must not be deceptive in any way. If you style the ad as a button or any 
other UI element in your app "A", and if it is not obvious that it is 
actually an ad, then you are violating that policy, because the user is not 
informed anymore. Their action of tapping the ad does not translate to the 
intended effect anymore. That means that your app ads must be recognizable 
as such probably by wording, appearance and also by the position on screen.

[android-developers] Re: SQLite case insensitive matching

[Nobu Games]

There rings a bell with your problem description. It's a while ago, but I 
remember now that I'm having similar problems with one of my apps and 
non-ASCII characters.
Since you are using the MATCH operator I assume you are also using the FTS3 
extension. I just found this piece of information on the documentation page 
for FTS:

*All uppercase characters within the ASCII range (Unicode codepoints less 
> than 128), are transformed to their lowercase equivalents as part of the 
> tokenization process. Thus, full-text queries are case-insensitive when 
> using the simple tokenizer. *
>

(source: http://sqlite.org/fts3.html#tokenizer)

That may explain why French accented lower-case letters are not correctly 
matched against their upper case equivalents, since they are effectively 
ignored by the default tokenizer. The same page mentions further down that 
the "unicode61" tokenizer implementation solves that problem correctly, 
however it looks like it is only available for FTS4, which in turn is only 
available since Android ICS (see 
http://stackoverflow.com/questions/6339022/sqlite3-fts4-match-and-android).

A dirty workaround would be to create an "OR"ed match query for both upper 
case and lower case versions of accented letters:

SELECT * FROM MyTable WHERE content MATCH 'Écuter OR écuter'

This however can get out of hand the more accented letters are contained in 
your search query. But if the data in your database is written according to 
standard writing rules (all lower case letters except for titles and words 
at the beginning of a sentence) you could focus just on the first letter of 
the search term for creating those "OR"ed match queries.

[android-developers] Re: Android Studio needs "create library" function! And Android needs a different OS Name!

[Nobu Games]

I had a similar problem with wrapping my head around this libraries issue 
when I started using Android Studio and Gradle just a few weeks ago (see 
discussion here 
,
 
also for an overview of the available options). You would usually add 3rd 
party libraries as module dependecies to your app project (hit F4 and go to 
"Dependencies" tab, click the green plus icon and select "Library 
dependency"). An online repository is searched for the requested library 
(also taking the requested version number into account). As far as I 
understand, that library will be downloaded once into your local Maven 
cache, which will be used by all your app projects. So in this case there 
should be no redundancy.

When it comes to self-developed library modules you can do the same. I get 
around this module-inclusion problem by deploying development snapshots of 
my own libraries into my local Maven repository and adding them to the 
dependencies list of my Android app. No redundancy here. Libraries can be 
centrally maintained and developed outside the app project. The same with 
3rd party libraries, they also can be added as dependencies from online 
repositories. The whole project organization and setup is driven by Gradle 
build files. You are free to configure it any way you wish.

I do not quite understand the system property problem and I think there's 
also no point in requesting any change. Android updates are super-slow to 
roll out and it would take many years until you could rely on that feature. 
A library that interfaces with the Android API is also usually compiled 
against the Android SDK, so the programmer should be well aware of the 
presence of Android. Unless you access the Android API via reflection, but 
in this case you can just use reflection to figure out that your code is 
running on Android.

Re: [android-developers] Re: What is wow factor about android studio in compare to Eclipse.

[Nobu Games]

Yesterday I tried to set up a web project in IntelliJ IDEA 14 CE and 
Android Studio. It did not work because all the necessary plugins are 
reserved for the commercial version of IntelliJ IDEA. Which is fine with 
me. They are running a business after all.
But I guess that may prove your point. It's not really an entirely "open" 
IDE and not entirely Open Source, since some features are locked away 
behind a paywall and the community does not deliver Open Source 
alternatives, yet.
Anyway, after two weeks of daily use of Android Studio I have to agree with 
what kj said. I prefer IntelliJ over Eclipse because of so many little 
things.

To be on thread topic here: the features that "wow" me most at the moment 
are the intelligent code completion 
, 
the resource value previews (strings, constants, drawables) that are 
embedded directly in the source code, and the whole "project configuration 
through Gradle build files thing". Kind of neat.

What drives me nuts at the moment are the bugs. The logcat view is always 
empty for me and makes the IDE unstable when open. Android Studio also 
tends to slow down my machine after a few hours of work. And my biggest pet 
peeve are the default keyboard shortcuts that are not entirely suitable for 
work on KDE, since some are already defined there. I also do not understand 
why the default shortcuts are so deliberately non-standard. But other than 
that I'm happy with Android Studio.

That's actually a very good point. I would deliberately allow redundancy to 
guarantee that a library works within an app project. As soon as the 
library is ready for prime time I can merge the changes back to the 
original repository and decide later if I need those changes in other app 
projects. It just makes the OCD part in me cringe a bit :-D

I'm not sure but I believe this could probably be the ideal solution to 
satisfy my "OCD needs". I would have a central development repository for 
my library modules and add specific versions of them to my app projects. 
With Gradle it's just a matter of adding a dependency statement. That way I 
could also guarantee that my apps do not break when I make changes to my 
libraries without having to duplicate library code. It's just super 
cumbersome when I want to develop locally for a while. So I guess I'd start 
out the way you describe and have library modules as part of the app 
project. When the library is stable I could merge it back to the 
originating repository and create a release build for Maven and add that 
build version as a dependency to the app project.

[android-developers] Reusable code organization with Android Studio

[Nobu Games]

I've been pulling out my hair over this in the past two days and searched 
the Internet for best practices when it comes to organizing reusable code 
in an Android Studio project. Coming from an Eclipse development background 
it's not really all that intuitive to understand. This post is a bit 
longer, so bear with me.

*TL;DR:* *What's your best practice when it comes to module organization 
and version control?*

The way I organized code so far using Eclipse for development and Apache 
Ant for building projects allowed me to easily keep the app project 
separate from its library projects. They could reside in different 
directories that belong to different version control system repositories. 
Now with Android Studio and my limited understanding of Gradle and the new 
build process I am basically forced to have all so-called library 
*"modules"* arranged as sub-directories of the main app project directory. 
In terms of code organization I have the following options:

   - *I use only a single massive repository *that is basically an Android 
   Studio project that hosts all my Android app modules and custom library 
   modules
  - This is not going to happen
  - I keep app projects in separate repositories and *I import my 
   custom library modules*
  - 
*Importing a module creates a copy of the original *
  - This means *redundancy* and *code synchronization issues*. I may 
  forget to merge back changes I've done to one of the library modules
  - Unfortunately this is the "official" solution provided by the 
  IntelliJ IDEA documentation 
  

  - I keep app projects in separate repositories and *check out my 
   library modules from a separate repository as a Git submodule 
   *
  - I *cannot cherry-pick the needed library modules* from the Git 
  repository. Git submodule checks out the whole library repository
  - It does not play nicely with that one level deep project/module 
  directory structure for Android Studio projects
   - I set up a *Maven repository for my library modules* and add the 
   needed modules as dependencies to my app project
  - Very elegant, but...
  - Every single tiny change in my library code requires rebuilding and 
  deploying the module.
  - I also fear that I need to increase the version code / build number 
  every single time so the local Maven cache gets updated? I have no 
  experience with this. :-/
  
*Here is what I am currently doing* and I'm not sure if it's good enough or 
can be considered a best practice:

This is my directory structure for app projects:
\ projects
\ my-android-libs   (checked out from library modules repository)
\ module-1
\ module-2
\ ...
\ App-1 (checked out from App-1 repository)
\ app
\ ...
\ App-2 (checked out from App-2 repository)
\ app
\ ...

As suggested in this post , in 
any of those app projects I need to alter the settings.gradle file and add 
the desired module dependency like this:

include ':app'
include ':module-1'

project(':module-1').projectDir = new File(settingsDir, 
'../my-android-libs/module-1)

Then I also need to add to the app module's build.gradle file a "compile 
project" statement to the dependencies list:

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:appcompat-v7:21.0.3'
compile project(':module-1')
}

This workaround works so far and right now it's the "lesser evil" for me. 
However, I'm still totally new to Android Studio, Gradle and Maven and I'd 
like to hear if you guys know some best practices when it comes to module 
organization, project setup and version control. I'm especially interested 
if anyone of you goes with the private Maven repository solution and how 
that works for you.

[android-developers] Re: How to implement crossfade texture effect in Opengl?

[Nobu Games]

OpenGL ES 2.x and higher are the way to go, so you probably won't get 
around coding your own shaders. That comes with a lot of advantages and a 
few problems. Yes there are some compatibility issues but they are 
universal and also affect desktop GPUs due to subtle inconsistencies in 
driver implementations. The article you linked to points out the main 
problems I also encountered. However, those issues do not mean that you 
should avoid using the OpenGL ES 2.x and higher. Take it as a list of best 
practices to follow.

You should also read through the following blog about OpenGL ES programming 
for Android: 
http://www.learnopengles.com/android-lesson-one-getting-started/
The articles there also explain how to bind textures, prepare and upload 
vertex data and so on. I hope they will answer your other questions. In my 
experience you won't run into big problems with most basic shader 
approaches. That cross-fading effect should not cause any issues.

[android-developers] Re: How to implement crossfade texture effect in Opengl?

[Nobu Games]

Never tried that myself but from OpenGL ES 2.x you could assign two 
textures to a fragment shader that gradually achieves that blending effect 
over time. The simplest blending effect would be linear, which has the 
basic formula:

P_mix = P_a * (1 - t) + P_b * t

where...

   - P_a would be the RGB color channel values of texture A
   - P_b the color channel values of texture B
   - t would be a time factor ranging from 0 to 1 and
   - P_mix is the blended result.


Now my GLSL skills are a bit rusty at the moment. It may look like the 
following (without any lighting calculations):

uniform sampler2D texA;
uniform sampler2D texB;
uniform float t;

varying vec2 texCoord;

void main() {
vec4 pA = texture2D(texA, texCoord);
vec4 pB = texture2D(texB, texCoord);
vec4 pMix = pA * (1.0 - t) + pB * t;
gl_FragColor = pMix;
}

>From your host app you'd need to animate the uniform value t over time.

Re: [android-developers] Re: Free App suspended for adding Google Analytics?

[Nobu Games]

You could in fact (try) to get around Google's payment processor if you 
change your donate button into an in-app purchase of a media file that can 
also be processed by other apps (images, videos, songs, eBook...), see Google 
Play Developer Policies 
:

Developers offering additional content, services or functionality within 
another category of app downloaded from Google Play must use Google Play's 
in-app billing service 
 as the method 
of payment, *except:* 
   
   - where payment is primarily for physical goods or services (e.g., 
   buying movie tickets, or buying a publication where the price also includes 
   a hard copy subscription); or 
   - *where payment is for digital content or goods that may be consumed 
   outside of the app itself (e.g., buying songs that can be played on other 
   music players). *


The only difficulty would be communicating the message to your users that 
the purchase is meant to be a donation for your work on the app. If you 
would phrase it like that you still would be violating the policies.

[android-developers] Re: insane ScrollView problems

[Nobu Games]

I'm not sure if that's just a copy & paste error, but you close the 
LinearLayout tag prematurely. So all its attributes including layout_width 
just count as "unexpected text":

You can easily spot these mistakes by running Android's excellent lint 
tool. If you are using Eclipse for development you should see a yellow 
warning triangle show up at that spot.

Re: [android-developers] Re: Physical address is required for paid apps or in-app purchases

[Nobu Games]

I added all information on both tabs, with the same address, since I'm 
running a business. The legal profile is likely just between you, Google 
and the authorities which will be contacted by Google to validate your 
business.

The public profile is probably the one you want to be careful with, if you 
want to hide your home address. In my experience, the legal profile is the 
more important one. It should be absolutely identical with whatever records 
you have filed with your bank and tax authorities. In my case Google denied 
payment a few months ago because they found a tiny typo in my business 
address and they said they could not match it against the records of the 
IRS. It was something like a missing letter, so they are going to be very 
pedantic there.

it is that using a 3rd party payment processor such as PayPal is only 
forbidden when the payment is meant for the app itself or extended features 
and goods that can only be used / consumed with the app. According to those 
conditions it's probably also not allowed to ask for PayPal donations for 
your programming work, since that could be seen as a late payment for the 
app.
I would say that donations for a good cause unrelated to yourself and your 
app, are acceptable. To be sure you could either try and get in touch with 
the Google Play developer support team 
 or consult a 
lawyer.

By the way, there is an Android *donations* *library* on GitHub, that 
claims to support several payment processors:

I can recommend this book:

It covers various important topics in 3D game development and also explains

[android-developers] Re: WebView.setEmbeddedTitleBar gone in Jelly Bean? Which alternatives?

[Nobu Games]

Here is a follow-up since I am still getting emails from people around the 
world: the *titlebar-webview hack does not work* anymore and* it cannot be 
fixed.* That's why I deleted the project from Google Code. It was a nasty 
hack that exposed a hidden interface and was actually doomed to fail over 
time.

If you want to have a title bar view then please consider a fixed layout 
(title bar view permanently on top of web view) or try to create something 
along the lines of the NavigationDrawer component.

[android-developers] Re: Image captured from my app is rotated by default

[Nobu Games]

This is expected behavior, and Doug's assumption is right. JPEG images may 
contain EXIF data 
blocks that also specify the orientation of the image. On your server 
you need to read the orientation data and use it to rotate the image into 
the opposite direction. If your server code is written in PHP you can use 
the Imagick library and the following functions for determining the 
orientation and rotating the image 
respectively:Imagick::getImageOrientation(),
 
Imagick::rotateImage()
.
If the server software is written in Java you could use a library such as 
Metadata-Extractor  for 
reading the orientation and any image processing library of your choice for 
rotating the image.

[android-developers] Re: forcing more GC_FOR_ALLOC

[Nobu Games]

Could you tell a bit more about the game:

- What Android version are you testing on?
- Do you draw graphics using OpenGL ES or Canvas?
- How many bitmaps or textures do you use at a time?
- What's the average resolution and bit depth of your bitmaps / textures?
- Do you scale or process bitmaps on load, if so how does that code look 
like?
- Do you also use MediaPlayer / SoundPool? If yes how many instances of 
them and how many sounds are loaded into your SoundPool? What are their 
bitrates, mono/stereo?
- Do you get that OOM exception while creating a new bitmap object?

[android-developers] Re: ANR from internal function

[Nobu Games]

I guess the solution is trying to debug the heck out of it, that's also 
what the OP was basically asking for. The causes in her/his case will most 
likely be too different to be useful for you, since I think it's related to 
multithreading deadlocks due to bad locking / synchronization. I had 
similar problems in my last game, because I screwed up at some places. 
Proper thread synchronization can be subtly difficult to implement.

What you could do is running your app using a debugger. As soon as the app 
gets unresponsive, look into the list of currently active threads that 
belong to your app process (in Eclipse that would be in the debug view in 
the debug perspective). As far as I recall, locked up threads are marked as 
"waiting". You should be able to see the currently executing method names 
and complete call stacks per thread. Their locations in code may give you 
hints what's causing the problem. You also may have to pause your app in 
order to avoid that crash happening.

[android-developers] Re: Activty on orientation

[Nobu Games]

By default the activity gets recreated on certain events such as 
orientation change. This is, as far as I know, the preferred behavior. You 
can handle these so-called "runtime changes" (such as orientation change, 
but there are more events that trigger activity re-creation such as changed 
system language) yourself by specifying the android:configChanges attribute 
of your activity in the manifest XML file. Handling orientation changes 
yourself will basically tell Android not to re-create the activity in case 
of an orientation change, and therefore your view hierarchy will be 
retained. See 
herefor
 more information.

[android-developers] Re: LVL: possible to check license for a different app?

[Nobu Games]

Educated guess: the UID may be the app's user id (UID). As far as I know, 
Android creates a unique user for each installed app for enforcing 
app-specific file system permissions. The licensing service probably checks 
that the requesting app process' user id matches the user id for the 
requested package. So it looks more like a security check and I'd assume 
that you cannot work around that, unless you'd run your request as that 
other user. And that's probably only possible on a rooted device.

[android-developers] Re: Home screen icon ads

[Nobu Games]

It could be just about any app that uses some ad(ware) SDK. As far as I 
know doing that kind of thing also requires a specific permission (

com.android.launcher.permission.INSTALL_SHORTCUT). So you could look through 
your list of installed apps and look for one with that permission.
Maybe there are also AdWare scanner apps that can automate that search for you.

[android-developers] Re: licensing - ServerManagedPolicy not caching

[Nobu Games]

Actually Google isn't doing their developers any favor with the LVL. The 
documentation reads like it is meant to serve as a drop-in solution that 
adds reliable DRM to your paid app. Just configure it a little bit with 
some policy and your "app is safe". On the other hand there is that lengthy 
Google 
I/O 
talkand
 some 
official blog 
poststhat
 discourage from using the LVL "as is", since all its components are 
known and a cracker can easily find them in your decompiled Java code and 
just remove them. The LVL is more of a proof of concept that should give 
you ideas how to interface the Play licensing service. That means changing 
and rewriting the whole LVL up to a point where the original is not 
recognizable anymore and at that point you understand every single bit of 
it yourself and don't run into that policy problem anymore, because you'd 
implement that policy yourself.

I voiced my opinion about the LVL and DRM here in the past and I used to be 
in favor of all these efforts. But trying to do it as properly as possible 
is a lot of additional overhead (it took me almost a week the first time), 
and when not done properly it either does not protect your app at all and / 
or pisses off legitimate customers. So I decided to get rid of any kind of 
DRM in my products altogether. It makes me sleep better because I know that 
it won't accidentally accuse one of my paying customers of theft just 
because I may have done some silly mistake. And in the end, if your app is 
interesting enough someone will crack it anyway. I guess it's more 
important to focus on those people who are willing to pay for your work and 
services. And maybe it really does help to see those cracked copies as some 
kind of free advertisement for your name and brand.

If you still want to implement DRM for your app, then watch that video I 
linked above. It's probably as in-depth as it can get when it comes to the 
LVL.

[android-developers] Re: CSS Height % Not working in Android App Screen

[Nobu Games]

I'm not sure if this is the cause but I noticed that your sample HTML page 
is missing a view port meta tag, which is commonly used in mobile web 
pages. The rendering logic is a bit different in mobile browsers due to the 
smaller screen size of mobile devices. Here is an explanation of mobile web 
browser view ports: http://www.quirksmode.org/mobile/viewports2.html

You have to add a meta tag to your HTML page header that tells the mobile 
browser something along the lines that the view port has to match the 
actual device screen width. Here is a Mozilla documentation page that 
explains it very well:

https://developer.mozilla.org/en-US/docs/Mozilla/Mobile/Viewport_meta_tag

[android-developers] Re: Rating Hijacking !

[Nobu Games]

I'm still far from being top or even mid-tier in terms of app downloads but 
this morning I also got my first 2-star mystery rating for a paid app of 
mine - no comment and no Google+ name I could respond to. That didn't 
happen to me so far since most users tried the free version first and then 
decided to buy afterward.

This wouldn't have bothered me that much but nevertheless I wanted to see 
for myself how that "recommendation rating widget" looks like on my phone. 
So I opened the Google Play store app and scrolled down the lengthy front 
page with several swipe movements. And I suddenly saw that an image was 
flashing and quickly changing to "1 star". I accidentally rated some random 
app while swiping the screen.

This bug 100% reproducible:

   1. Touch one of the stars
   2. Move your finger up or down outside the recommendation box
   3. Lift finger
   4. App gets rated
   
This can happen quickly and accidentally while scrolling down the screen. 
Since I am right-handed (as the majority of people), my thumb naturally 
reaches to the left side of the screen, where the worse rating options are 
(1 and 2 stars). I bet this happens thousands of times every day without 
people even realizing what they just did. I sent a bug report to Google 
Play support about that issue.

I also have to agree that the phrasing of the recommendation is completely 
misleading. If it weren't for this thread here I would have thought that 
I'd be rating recommendations and not apps. If I were asked to rate my 
favorite "scanner app" with the question "rate this item to get 
recommendations", I would give that recommendation a bad rating because I 
am already 100% happy with my scanner app and I'm absolutely not interested 
in more apps like that. I guess something along these lines may have 
happened with my paid app this morning.

Google Play really has to fix that as quick as possible. This new 
recommendation widget is a substantial change in the overall rating system 
Google had no experience with before. Stuff like that should be extensively 
tested before put into production mode. Real users should have been 
observed while interacting with that new widget. Real users should have 
been asked how they interpret the meaning of that new feature. To make that 
feature more useful it should be either decoupled from recommendations and 
be absolutely straightforward: "Do you like this app? Rate it". If 
recommendations are more important than that then it should be a simple 
thumbs up / thumbs down and the result must not affect the rating of the 
recommended app.

[android-developers] Re: Android how we can free the RAM memory of the device.

[Nobu Games]

I could imagine that forcing the OS into a low memory situation might 
trigger what you want. By temporarily allocating large blocks of memory 
from native code (using the NDK) the OS may try to stop background apps and 
services which in turn will free their claimed resources and RAM. Don't 
forget to free your allocated memory.

[android-developers] Re: WeakReference containing callback interface

[Nobu Games]

Why don't you check your progress bar if it's null before modifying it? If 
the progress bar got garbage collected it's safe to say that it is not 
there anymore (not visible) and any modification wouldn't make any sense at 
that stage.

[android-developers] Re: Fog color does not work in Jellybean!

[Nobu Games]

Try to debug by retrieving the GL error code:

Log.d("GL Error", gl.getErrorCode());

When the value is non-0 then there is an error. You need to identify the GL 
function call causing that error state. You could for example add a logging 
output line after each GL function call like this:

gl.glEnable(GL10.GL_FOG);
Log.d("Enable fog", gl.getErrorCode());
gl.glFogx(GL10.GL_FOG_MODE, GL10.GL_EXP);
Log.d("Set fog mode", gl.getErrorCode());
gl.glFogfv(GL10.GL_FOG_COLOR, fogColorsBuffer);
Log.d("Set fog color", gl.getErrorCode());

If you get a non-0 number you need to look up the meaning of that error 
code.

Re: [android-developers] Re: .db files being renamed to .back

[Nobu Games]

The SQLite documentation says that the 
maximum database file size is 2,147,483,646 pages
A single page can range from 512 to 65,536 bytes. So the minimum page size 
configuration would yield a maximum database file size of 1 TB. So 
something else is going wrong here.

Out of curiosity I checked the vanilla SQLite C source code for occurrences 
of ".back" and could not find anything. Just a vague guess: it looks to me 
like some odd kind of data corruption recovery handling. In older versions 
of Android the strategy was just deleting the corrupted database file and 
starting from scratch. It could be a vendor-specific customization or maybe 
a different firmware like CyanogenMod.

But I think it's more likely that your customers who report that problem 
are to blame. Probably by misusing some file manager or backup software as 
gjs already mentioned :-/

Could they recover their data by renaming these ".back" files to ".db"?

[android-developers] Re: why does SharedPreferences framework allow you to insert a preference with a null key - given it can't reload the preferences afterwards?

[Nobu Games]

I quickly peeked into the source code and well, this is the way how it is 
programmed. When an exception occurs while the preferences data file gets 
read, SharedPreferences sets internally an empty map so you start from 
scratch. I even dug a bit deeper. The XML serializer just ignores NULL keys 
and creates XML output that cannot be properly read anymore through the map 
deserialization method which seems to expect an existing key value.

As for why it has been programmed like that... I think the reasoning may be 
that preferences are not deemed to be of so much importance that it should 
make the app crash in case of failure. This error state is silently 
discarded and you start over with the defaults. I think that's a reasonable 
approach since any app should be able to start over with empty preferences.

In this particular case you may have discovered a tiny bug you may want to 
report. But to be honest, using null keys is a pretty unusual thing to do.

[android-developers] Re: "Not Licensed for this country" when paid app used in another country?

Are you sure your Australian customer had the app still installed on his 
phone? Maybe he tried to reinstall it during his stay in the US and the 
error message was actually from Google Play. What 3rd party libraries are 
part of your app?

[android-developers] Re: Signed APK corrupt on deploy. FC with Class Not Found exceptions

[Nobu Games]

If it just happens with the release version this may be a ProGuard 
misconfiguration issue. "Class not found" and "Method not found" exceptions 
are symptomatic for that. Check the exact exception message for the class 
name that couldn't be found. Make sure that your release build really 
contains that class (it may be part of a linked library or JAR file, make 
sure that it really gets included with your APK, there are various ways and 
tools for doing so like dex2jar). If it is in fact an obfuscation problem 
you need to add ProGuard rules for protecting this class (and probably 
others, too) from being obfuscated.

[android-developers] Re: NDK: faster alternative to JNI based custom rendering

[Nobu Games]

As you already pointed out, floats can be a bottleneck. In many cases it is 
possible to rewrite graphics algorithms in a way to make exclusive use of 
integers. You need to get rid of the fractional part and that can be done 
by scaling up all values depending on your needs for the precision. When 
all calculations are done you need to scale the numbers down again. 
Multiplications and especially divisions can be expensive, too of course. 
When your scale factor is a power of 2 you can use bit-shifting instead of 
multiplication and division which is computationally as cheap as it can get.

I wrote a small image processing and drawing library a while ago and wrote 
all algorithms to make use of integers. In case of convolution matrices it 
was possible to speed up the calculations up to 3 times compared to their 
floating point counterparts.

Another speed optimization trick is precomputing a table of reoccurring or 
known terms and values. This can be done with gradients for example. What I 
didn't dabble with yet is ARM's NEON extension. I read all over the place 
that (if used correctly) it can give you another significant speed boost. 
GCC provides some 
intrinsicsfor the 
extension. And as far as I know you can also tell GCC to 
automatically optimize for NEON. Since not all ARM CPUs are equipped with 
that extension this may be dangerous, though, unless you  create a version 
for NEON and a standard version and determine on runtime which one to load 
and use.

Android's 
RenderScriptmight
 be a pretty fast solution, too, but I'm not sure if you'll be able to 
easily convert your drawing algorithms to make it work with it. It's 
basically pretty good at crunching numbers and quickly running convolution 
matrices for image processing by using the GPU and theoretically all 
available CPU cores.

[android-developers] Re: Activity partially offscreen

Hm... you could get the top level container view from the Window component 
and transform that view. The transformation probably needs to be done with 
a translation animation. However, you'll also need to catch and change 
touch events since their coordinates will be off.

[android-developers] Re: Upgrading Apk

[Nobu Games]

There is no fix and no workaround. Even if Google Play would allow you to 
upload your APK signed with a different key, Android devices would refuse 
to install your update because of that mismatch. If you are really sure 
that you cannot find your old keystore then you have to publish your update 
as a new app with a different package name.

[android-developers] Re: Show Glyph outside Unicode Range ? label:Android

[Nobu Games]

I don't think that Android's typeface component or TextView allows 
switching to different variants. If your font does not have a mapping from 
that glyph to a Unicode code point then you probably won't be able to 
render it.

If you have a font editing application you could extract that glyph and 
assign it to an ordinary "1" :-/

Interestingly enough the original code does not explicitly throw the 
exception you mentioned. So it must be some weird Samsung hack. You could 
try registering with Samsung as a developer and use their support ticket 
system in order to tell them about this problem. However, I already 
complained once about one of their SDKs and never heard back from them.

Maybe as a hex dump?

I'm not sure if I understand you correctly, but the following homepage 
contains documentation about the Google+ API including their HTTP-based API 
which allows you to roll your own client implementation in any language you 
want:

[android-developers] Re: Should SQLiteDatabases be limited to 2Gig?

[Nobu Games]

I just did some digging around and your error code translates into the 
following define constant: 
*SQLITE_IOERR_FSTAT*

So basically it's an fstat error which according to this 
threadcan
 happen when you try to access the database after it (or one of the 
journal files) have been deleted. 
Othersalso mention that 
this error has to do with changing data while another 
thread is trying to read it simultaneously. I guess the "write-ahead" 
journaling of SQLite does not mix well with thread concurrency. In my 
experience you should try to synchronize all concurrent read and write 
access to your SQLite database yourself and not rely on the built-in 
locking facilities (they never worked for me correctly).

PCM is basically uncompressed audio data. MP3 is compressed audio that's 
why you hear noise. You have two options for solving that problem:

1. Decode your MP3 stream on the fly and feed it to your AudioTrack
2. Use

 of AudioTrack

[android-developers] Re: SQLiteException: error code 5: database is locked. When accessing ContentProvider from AsyncTask

[Nobu Games]

This error can happen when you try to open the same database (file) 
multiple times. Which in turn can happen when you are using multiple 
instances of SQLiteOpenHelper. So where do you create the instance of 
"database"?

[android-developers] Re: Detect a gesture startet from the outside of a view

[Nobu Games]

You could still try the approach I described by getting rawX and rawY from 
the motion event and match it with the global rect position of the target 
view. Motion event coordinates are usually in a local coordinate system. I 
guess the local coordinate system is the one of the ImageView you start 
your gesture with, hence the too big numbers when you get your 
ACTION_CANCEL on the other view.

[android-developers] Re: SurfaceHolder.setFormat() only working when called from the *wrong* thread?

[Nobu Games]

I'm not sure if I understand you correctly when exactly you set the format. 
It sounds too me as if you're setting it "too late", after the OpenGL ES 
context has been created.

What I do is setting the format in the Activity's onCreate method on the UI 
thread before the OpenGL context is initialized and before a renderer has 
been set. Maybe your setFormat call is postponed in a way so you lose the 
OpenGL context and it forces a re-creation? I guess it just works for you 
on different devices because your call to setFormat does not actually 
change the format, so nothing happens. Your older 2.2 Android device may 
have a different default format for the surface view (such as RGB565) 
compared to newer devices.

[android-developers] Re: Detect a gesture startet from the outside of a view

[Nobu Games]

Is it just gestures or are you trying to implement drag and 
drop(because it 
sounds like that). Either way you could just intercept motion 
events in the parent view group that contains your images and let it handle 
your gesture recognition.

So let's say you create a derivative class "L" of your layout that contains 
the image views.

You could override 
dispatchTouchEvent(MotionEvent)of
 L and check for the following motion event states:

*1. Gesture started (ACTION_DOWN)*
Iterate your list of ImageView children of L and see if the touch event 
point is in one of them. If yes, your gesture starts.

The View class has the method getGlobalVisibleRect(Rect, 
Point)which
 can be used for checking if your touch event coordinate hits one of 
your image views. It would roughly look like the following (not tested 
since I'm not sure if these methods return locations in screen or window 
coordinate system, you may need to debug it):

*Rect* r = new *Rect*();* *// should be class member you can reuse
> float x = motionEvent.getRawX();
> float y = motionEvent.getRawY();
>
> *for*(*ImageView* iv : imageViews) {
> iv.getGlobalVisibleRect(r);
>
> *if*(r.contains(x, y)) {
> // Touch event is inside image view
> }
> }
>

*2. Gesture ongoing (ACTION_MOVE)*
If you visualize your gesture by drawing some trail or moving around the 
first touched image view then this is the right point to do so. Here you 
can update your view(s).

*3. Gesture finished (ACTION_UP)*
Here you need to iterate your ImageView children again in order to see if 
the finger has been lifted over another image view. In that case your 
gesture was successful.

*4. Gesture canceled (ACTION_CANCEL)*
Whatever your gesture is doing should be canceled here.

[android-developers] Re: Designing Help into Your App

[Nobu Games]

Personally I always go for option 2, a full screen webview in an extra 
activity for displaying help for the current page. I store localized HTML 
files in the assets directory. It's just a matter of adding some language 
code to the file names and loading the correct page for the current locale 
while falling back to English. It works so far for me.

I also agree with what TreKing: it's not a top priority for most 
developers. But in my humble opinion they probably shouldn't write the end 
user documentation of their own apps in the first place. First of all 
because of some kind of blindness when it comes to possible real help 
questions. They know their babies inside out. Second of all documentation 
written by programmers tends to sound way too technical. I guess it's 
better to let somebody who isn't that technical but good at writing do that 
job. And that person should try to figure out the app with a fresh pair of 
eyes.

Ultimately I don't think that users really care that much about detailed 
context-sensitive help texts because of "*tl;dr". *Most users require the 
app to be self-explaining. At best there should be some easy to understand 
tutorial overlays that explain UI elements with arrows and short texts.

In an early version of my latest game I tried to "force" the player through 
a 4 minutes tutorial that explains with an animated character every aspect 
of the game. I was thinking that ought to be alright and digestible for a 
one-time experience. But my beta testers felt bored and complained about 
that. So I went with that overlay mini-tutorial approach. No more 
complaints.

[android-developers] Re: Black screen on Samsung Galaxy S4 mini

[Nobu Games]

Is it an OpenGL ES live wallpaper? Does your code check OpenGL for error 
codes?
 
As far as I know these errors do not get logged by default. It may be just 
about anything like OpenGL running out of memory while trying to upload a 
texture or something like that.

[android-developers] Re: Add a contact via ContentProvider programmatically

I'm not completely sure but I think you need to create separate inserts for 
the name and the phone number. So make a separate insert for the phone 
number and don't forget to set the correct mime type for that.

[android-developers] Re: Can not debug Galaxy s4 mini

[Nobu Games]

Does your phone show some popup message when you try to debug it from your 
PC? Beginning with 4.2.2 there is a "secure USB debugging" feature. You 
have to explicitly authorize a host computer: 
http://android-developers.blogspot.com/2013/02/security-enhancements-in-jelly-bean.html

If you set up your phone with multiple user accounts make sure to switch to 
the primary user count (the first one created) to see that opt-in message.

[android-developers] Re: drawBitmap Flip, Scale and Translate

[Nobu Games]

Keep in mind that the origin of a bitmap draw operation is the upper left 
corner of the bitmap. So is the origin of canvas (unless you change it with 
a transformation matrix).

When you tell canvas to render everything flipped horizontally and draw the 
bitmap on the canvas at (0;0) the bitmap will be rendered outside the 
canvas to the left. Just imagine that all pixel coordinates of canvas are 
multiplied by your scale values. Your x-axis scale value gives every 
pixel's x-coordinate a negative sign. So every pixel on the visible side of 
the canvas is flipped alongside the left edge of the canvas and become 
invisible. You need to translate the bitmap horizontally to compensate for 
that.

You can set an additional postTranslate on the transformation matrix. Or 
you could set the x-coordinate of the bitmap draw operation accordingly.

Matrix flipmatrix = new Matrix();
flipmatrix.setScale(-1, 1);
flipmatrix.postTranslate(-canvas.getWidth(), 0);

I haven't tried that myself and I'm sometimes also a bad with affine matrix 
calculations. I'm not sure about the negative sign of canvas.getWidth() so 
you probably need to play around a bit with that.

You also probably should try a plain bitmap draw operation without source 
and target rect but just coordinates in order to see if that works for you.

[android-developers] Re: Which niche of Android app generates the most revenue or is likely to generate the most revenue in the future?

[Nobu Games]

Following AppBrain statistics show that the top ranking categories are 
personalization and entertainment:

http://www.appbrain.com/stats/android-market-app-categories

I'm not sure if there is any noteworthy niche in these categories. There 
are always trends and copy-cats of successful products. I guess the only 
real key to making money with apps is being able to provide a quality 
product, regular updates and continuously promoting it with a solid 
advertising plan and budget. It's usually not done with just releasing the 
app and announcing it on a few forums and social websites. As with all 
things related to business: you have to have money in order to make money.

Talking about most revenue... I read a few articles on Gamasutra where 
mobile app developers swear on "freemium" (free download with in app 
payments for feature upgrades).
Here are various opinions on that matter from different game developers:

Re: [android-developers] Re: How to animate a bar which grows in height

[Nobu Games]

I'm not sure if that really works properly with animations, since I'm not 
sure how and if they trigger re-layouts. But in theory you could try 
android:gravity="bottom" in your RelativeLayout or use  
android:alignParentBottom="true" in your bar child views.

If this doesn't work, you may have to bite the bullet and create a custom 
view that just renders your bars the way you need it. But maybe someone 
else has a better idea.

[android-developers] Re: How to animate a bar which grows in height

[Nobu Games]

Hi Daniel,

can you post the layout in which these bars are embedded? You may be able 
to solve it with some "bottom gravity" setting in the parent container 
layout

[android-developers] OpenGL ES 1.1 with alpha channel

[Nobu Games]

I have a problem with setting up OpenGL ES 1.1 with alpha channel support.

First of all: I need an alpha channel within OpenGL ES for performing alpha 
masking and blending effects. My game uses a texture with alpha channel for 
masking another texture. This only happens to work when I initialize OpenGL 
ES with the following configuration:

glView.setEGLConfigChooser(8, 8, 8, 8, 0, 8);

I could use the stencil buffer instead and parts of my game do that, too. 
However, my Nexus 7 tablet crashes pretty hard with a colorfully distorted 
screen when I use the stencil buffer in conjunction with alpha testing 
(which is necessary for discarding transparent pixels in the masking 
texture):

gl.glEnable(GL10.GL_ALPHA_TEST);
gl.glAlphaFunc(GL10.GL_GREATER, 0.05f);

Romain Guy says 
herethat
 the alpha channel set in setEGLConfigChooser does not need to be used 
unless the window is translucent. However, when I compile my game with:

glView.setEGLConfigChooser(8, 8, 8, 0, 0, 8); // alpha = 0

My texture masking effect does not work anymore. Instead I can only see the 
unmasked texture hovering as a square on the screen. All other textures 
with alpha channel are rendered correctly but only when I don't try to 
alpha-mask them.

I could leave the configuration with 8 bits alpha channel. However, then I 
get on some older devices crashes with an EGL_BAD_MATCH  error because 
their surface view apparently only supports RGB565 or maybe even something 
worse than that.

I tried fixing the problem as follows:

glView.setEGLConfigChooser(5, 6, 5, 8, 0, 8);

But that does not work either (config chooser cannot find a matching 
configuration). What can I do in this situation? How can I keep my alpha 
channel within OpenGL ES (I don't need it for the surface nor the window) 
and make older devices happy without crashing right on initialization?

[android-developers] Re: Need to show a dialog on top of all other Apps for a custom hardware.

[Nobu Games]

I played around with the Google Play Games Services SDK a bit and it looks 
like they also have such a kind of dialog that is able to be on top of 
everything else (and even survives activity transitions). It's the 
"welcome" log in message that pops up on top of the screen.

I'm not sure where the code for this popup resides. You may want to take a 
look at the SDK code, though I believe you may not be able find it there 
since it could be part of a system component (Play Services system app).

However, it seems to be possible to add a view to the window from within a 
service:

http://stackoverflow.com/questions/4481226/creating-a-system-overlay-always-on-top-button-in-android
and also
http://stackoverflow.com/questions/12650463/getting-window-display-from-service-android

The only problem is listening to onKeyDown from a service: 
http://stackoverflow.com/questions/3454710/onkeydown-in-a-service-global-hot-keys/3455094#3455094

I guess that would be the only thing where you need to implement your 
firmware customization in order to make that possible.

Re: [android-developers] Re: Gradle build is screwing up in weird ways on 5% of devices when used with Proguard -- same config and source works fine in Eclipse build

[Nobu Games]

I agree with you. And that also may be of concern for Eric Lafortune, the 
ProGuard developer. It could be that there is a glitch in his code 
obfuscation routines.

If it is floating point related you could try adding the "strictfp" 
modifier to your methods or classes that rely on platform-independent 
floating point arithmetics.

Re: [android-developers] Re: How do I flip images?

[Nobu Games]

Unfortunately not, it's simply too specific. In that case you may have to 
roll your own implementation, I'm afraid. Or better: just simplify your 
requirements and use a ViewPager for flipping your pages. It's just a 
horizontal scroll animation but it's ok.

[android-developers] Re: buggy legacy options menu on Samsung S4

[Nobu Games]

Sorry, I did not realize, there was a ZIP file. I was thinking the download 
button is just some big graphic and my "visual parser" in my head discarded 
it :-D

Your activity is as simple as it can get and I cannot spot any mistake. It 
really may be just some rare firmware glitch and nothing much to worry 
about. Unfortunately we have to deal with these random device-specific 
oddities all the time.

If you really want to work around that issue you could make use of an 
action bar and move the most important and relevant menu options there.

[android-developers] Re: How do I flip images?

[Nobu Games]

I was in the same shoes a while ago. There is no easy way to get a 
convincing animation. And you cannot get it at all using Android animation 
objects.

There are a few "page curl", "page flip" tutorials out there. It will boil 
down to creating your own view that renders it. And that's not really 
trivial to do especially when you want to make that "interactive" by 
dragging around the page and changing the curl dynamically based on the 
finger position. Maybe you'll find a ready made component for Android by 
searching for "Android page curl".

Re: [android-developers] [Market] Commenting unpublished application

[Nobu Games]

In response to my own question and for the public record:

Everybody who downloads a published (free) app still has access to the 
unpublished market page by opening the direct market page URL. You can 
still download it from scratch when the app is not there on your device and 
you can also update it.

It's pretty convenient, because I can still roll out updates for an 
unpublished app. People are apparently not notified through the Google Play 
app about it, but my app has its own update notification feature, so that's 
no big deal.

[android-developers] Re: Web search.

[Nobu Games]

Make yourself familiar with regular expressions and try to evaluate the 
input string for matching known URL address patterns. The problem here is, 
that your pattern matching must not be strict. So you also need to allow 
input like

www.domain.com
domain.com

without http(s) protocol prefix which will be the most likely user input. 
Unfortunately that is a malformed URL and you need to auto-complete it so 
it gets valid:

www.domain.com --> http://www.domain.com/

Everything that does *not *match your URL pattern should be treated as 
search query. You could pass on that query to Google or whatever search 
engine of your choice.

Re: [android-developers] [Market] Commenting unpublished application

[Nobu Games]

I wonder if this is still true, since Google Play changes the rules every 
now and again. Unfortunately I cannot find any official statement on that 
matter.

My problem right now is that I participated in an AppGratis campaign and I 
had to unpublish my app. However, people are still reporting bugs and I 
need to roll out updates somehow without re-publishing that AppGratis app 
on Google Play. Most users are not tech-savvy enough for side-loading APKs.

So are the following assumptions correct:

1. User downloads published app from Google Play
2. App is unpublished from Google Play
3. App gets updated while still being unpublished

A) User gets update through Google Play
B) User only gets updates as long as the originally downloaded app is 
installed on the phone
C) User does not get updates / cannot install app when she decides to 
uninstall or switches the Android device

[android-developers] Re: example source code or tutorial on using fragments and OpenGL ES 2.0

[Nobu Games]

Hi James,

as far as I know it's not (reliably) possible to have more than one 
SurfaceView(or
 GLSurfaceView) in one Activity at the same time. Since it sounds like 
you just want to draw graphs, it would be probably better to resort to a 
custom view component and drawing on a Canvas.

If you fancy OpenGL ES rendering capabilities then you should just have a 
single GLSurfaceView and implement swiping / paging yourself by capturing 
touch events and drawing the OpenGL ES scene accordingly.

[android-developers] Re: Fragments navigation and backstack issue

[Nobu Games]

Hi!

I remember the pain with fragments and the back stack while working on an 
app last year. My solution was the following. In the activity's onCreate 
method I would do the following:

FragmentManager fm = getSupportFragmentManager();
> fm.addOnBackStackChangedListener(new OnBackStackChangedListener() {
> @Override
> public void onBackStackChanged() {
> FragmentManager fm = getSupportFragmentManager();
>
> if(fm.getBackStackEntryCount() == 0) {
> finish();
> }
> }
> });
>

It basically listens to fragment back stack changes and forces the Activity 
to finish when the stack is empty

Re: [android-developers] Re: ContentResolver insert return null on 4.3

[Nobu Games]

Sorry Eli,

I should have read your code more carefully. You're hard-coding file paths 
in that insert request which is bad practice. You cannot assume that there 
paths like "/sdcard/..." on all Android devices. They can be named 
completely differently depending on device / manufacturer and especially on 
Jelly Bean there's  something like a "virtual file system" for supporting 
multiple user accounts and these file paths look totally different.

You should make use of the context.getExternalStorage(...) and related 
methods (also look into the Environment class).

Maybe the hard-coded file path is the problem there?

[android-developers] Re: GLSurfaceView lag/delay on Galaxy S3.

[Nobu Games]

Hi Edvinas,

I need to ask again, because I think that may be the cause of the delay: 
how do you communicate the touch events to your rendering thread? Because 
Android can bombard your UI thread with lots of touch events in no time. 
But your rendering thread needs to "peek" before updating the game state in 
regular intervals into the current state of touch input. It's your game 
loop / rendering thread that needs to dictate the rhythm in order to 
synchronize the "whole experience".

What I do in my game is the following:

1. Touch input event handler receives all motion events on UI thread
---> converts motion event data into a custom data structure and puts it 
into one queue that belongs to UI thread

2. Simultaneously the game loop / render thread updates the game state and 
checks for input first:
---> It requests the data from touch handler in a thread safe manner 
(synchronized)
---> Touch handler internally swaps motion data queue A with a 
secondary motion data queue B
---> Touch handler returns queue A to game loop
---> Game loop / render thread processes queue data and recycles all motion 
data structures (so they can be re-used in order to avoid garbage 
collection activity)

And that repeats like this and these two queues get always swapped. That 
way you let your game loop determine the pace.

[android-developers] Re: ContentResolver insert return null on 4.3

[Nobu Games]

I just had a quick peek at the API level 14 source code and it looks like 
there are two possible reasons for that problem:

1. The actual ContentProvider the ContentResolver connected to returns null 
on insert (for whatever reason, that is a mystery)
2. A RemoteException was thrown during the insert operation. The exception 
is caught by the ContentResolver and it returns just null instead. The 
reason for that is (according to the source code comment) that the process 
/ app is about to die anyway.

Other ContentResolver methods behave exactly the same. Also the query 
methods. It can - without a warning - just return null, even though it 
works in your tests a million times.

You therefore need to check the result for null and come up with a strategy 
for coping with that problem, like scheduling a re-query or checking if 
your activity is about to be finished.

[android-developers] Yet another EGL_BAD_MATCH problem. How to do it the right way? For all devices?

[Nobu Games]

I have another rather rare problem with OpenGL ES which has to do with the 
dreaded EGL_BAD_MATCH problem.

I do know that there is a correlation between the following factors that 
yield that problem and make the game crash:

1. The Android device is most of the time rather old with a dated Android 
version (API level 8 to 10)
2. I explicitly set the surface view holder's pixel format to RGB_888
3. I request the following configuration: setEGLConfigChooser(8, 8, 8, 8, 
16, 8); (I have to admit that I probably don't need a 16 bits depth buffer, 
but I do need the 8 bits stencil buffer)

What I have read so far about this problem is the following "silver bullet" 
solution: just create your own config chooser. I get that point. But even 
then developers say on some forums  that it crashes on some devices, so 
apparently it's pretty difficult to find a good matching configuration that 
doesn't make OpenGL ES crash.

How to approach that problem reliably without having all these gazillion 
Android devices at your hands? Is there a good recipe for that, like a 
solid generic implementation of a chooser?

Thanks in advance

[android-developers] Re: Do SQLiteDatabase references "go stale"?

[Nobu Games]

Oh my... when I think about that, I have a pretty old first generation 
Samsung Galaxy S (I9000). Its internal storage memory seems to be dying and 
quite a few apps behave erratically, including crashes and data loss. 
Sometimes it's stuck in an "infinite" reboot loop. So I'm pretty sure it 
won't last for too long.

I guess these are also probably things to watch out for when talking to 
customers (how old is their phone, do they store data on an external SD 
card, because these things can also break and silently corrupt your data. I 
lost a lot of photos and MP3s because of that :-)

It would be great if there were some system level tool for non-rooted 
devices to make a proper file system and storage integrity check...

[android-developers] Re: Do SQLiteDatabase references "go stale"?

[Nobu Games]

Just another related thought: SQLiteDatabase contains some implicit 
"transaction magic" under the hood which is meant to prevent "accidents" 
due to simultaneous accesses from different threads. That does not always 
work that great and can lead to some kind of indefinite deadlock situation. 
You can ease that problem by making sure to only give one thread 
"ownership" of the db connection by letting it open and query the 
connection.

You also must make sure not to open the same database connection multiple 
times. In older Android versions that error was not treated gracefully and 
the database file could get corrupted. In newer versions you are greeted 
with an exception. When the database file gets corrupted, the default 
behavior of SQLiteDatabase is "silently" dropping the whole database file 
and creating a new one, so basically you start from scratch in such a 
situation and probably your table creation / setup routines kick in and 
start fresh.

You can ease that problem by making sure to only give one thread 
"ownership" of the db connection by letting it open and query the 
connection. You could enforce that by implementing a content provider that 
is only used by your app.

You also must make sure not to open the same database connection multiple 
times. In older Android versions that error was not treated gracefully and 
the database file could get corrupted. In newer versions you are greeted 
with an exception. When the database file gets corrupted, the default

Re: [android-developers] Bizarre OpenGL ES rendering artifact on Nexus 7 with Android 4.3

[Nobu Games]

Hi Romain,

thanks for your reply. It seems I do not understand the surface view 
initialization for making the alpha channel within OpenGL ES work. I set up 
the surface view with:

glSurfaceView.getHolder().setFormat(PixelFormat.RGBA_);

The game is already out with that surface view setup since May and nobody 
complained about the graphics so far. It also got reviewed with screen 
shots and videos and so on and this artifact is nowhere to be seen.

I also do not understand why there is a difference in rendering between the 
APK downloaded through Google Play and the exact same APK locally installed 
via adb.

Should I change the surface view format to RGB_888 instead?

Regards,

Thomas
