Re: [android-developers] 2 Tasks are available after onRequestPermissionsResult().

[Daniele Segato]

I still don't understand your question.

You are mixing things you do in code with steps the user takes.

And you are not clearly stating what is the expected behavior you want and 
the behavior you get or what the problem is.

[android-developers] Google AppInvites beta cause MissingTranslation Lint error compiling in Android

[Daniele Segato]

This is a bug report. Couldn't find a better place to file this too, if you 
have a reference to the right forum/bug tracking I'll happily use it.

I wanted to try out Google AppInvites beta.

Not sure if this is a tool (gradle) bug or a Google Play Service bug.

I followed the steps here:
https://developers.google.com/app-invites/android/guides/app

When I launch my release build lint fail with a MissingTranslation on a 
generated values string file

The two strings causing the issue are:


[censured]
[censured]



:app:lintVitalRelease
[censured]
~~
[censured]/app/build/generated/res/google-services/release/values/values.xml
Error:(3) Error: "gcm_defaultSenderId" is not translated in "it" (Italian) 
[MissingTranslation]
Error:(4) Error: "google_app_id" is not translated in "it" (Italian) 
[MissingTranslation]
[censured]

   Explanation for issues of type "MissingTranslation":
   If an application has more than one locale, then all the strings declared
   in one language should also be translated in all other languages.
   If the string should not be translated, you can add the attribute
   translatable="false" on the  element, or you can define all your
   non-translatable strings in a resource file called donottranslate.xml. 
Or,
   you can ignore the issue with a tools:ignore="MissingTranslation"
   attribute.
   By default this detector allows regions of a language to just provide a
   subset of the strings and fall back to the standard language strings. You
   can require all regions to provide a full translation by setting the
   environment variable ANDROID_LINT_COMPLETE_REGIONS.
   You can tell lint (and other tools) which language is the default 
language
   in your res/values/ folder by specifying tools:locale="languageCode" for
   the root  element in your resource file. (The tools prefix
   refers to the namespace declaration http://schemas.android.com/tools.)
2 errors, 0 warnings


In my build.gradle file I've set: 

resConfigs "it"

The only way I found to build for release has been to set

lintOptions {
// google services plugin is causing missing translation issue
abortOnError false
}

still pretty annoying.

Please makes this bug report reach the right persons in Google or tell me 
how I can reach them properly.

regards,
Daniele

[android-developers] How to get Google Play Services currently connected account?

[Daniele Segato]

Hi,

Many Google Applications allow you to switch between Google Accounts and 
show you the currently connected account.

For example Google Fit, Gmail, Google+, etc...


>From the perspective of the code I call .connect() on the Google Client and 
enter a loop of
- connection failed
- launch automatic resolution
- get activity result
- retry connect

until I finally connect.
This is documented in many places, here for example: 
https://developers.google.com/android/guides/api-client

On the UX side what happens is that the user is presented with multiple 
dialogs asking every time something different.

One of the dialog ask to chose an Account between the ones available on the 
phone (it probably automatically resolve without user interaction if 
there's only one account configured).

How do you query the Google Client to know which account is currently 
connected?

I found no documentation about it anywhere.

The closest thing I found is this:
https://developers.google.com/android/reference/com/google/android/gms/common/AccountPicker

but I do not create the picker, it's something completely handled by the 
Play Services in the procedure I described above.

Thank you,
Daniele

[android-developers] Any Android M Preview official forum?

[Daniele Segato]

Hi,

I was looking for an Android M Preview forum: an official place to ask 
question on the new OS versions / user suggestions / user feedback.

Is there anything like it anywhere? (couldn't find)
I don't want to pollute this forum with that stuff.

[android-developers] Re: android character set

[Daniele Segato]

I also want to know this.

Roboto apparently do not support Chinese and Japanese (Hirigana, Katawana).

So which is  the list of supported character sets? (unicode group, scripts, 
whatever you want to call them).

And if Chinese/Japanese are actually supported: which font is used?

Re: [android-developers] Using the Expansion Pack for optional data

[Daniele Segato]

Hi Jeremy,

no. The expansion pack (either the main one or the patch one) is usually
downloaded with your application when the user install from market.

It can happen that is NOT downloaded but there's no option to tell the
market not to download it with your app.

Re: [android-developers] Criteria for .obb files download (GooglePlay vs manual)

[Daniele Segato]

There are probably many.

I can tell you one: network connection failure / disconnection while
downloading the obb file. The app installs anyway. The obb file has to be
manually downloaded.

Very slow connection detected etc... Behavior can change since the Google
Play app upgrades itself on its own.
So stop asking yourself if that can happen in your app and just implement
it properly.

regards,
Daniele

Re: [android-developers] developing with higer sdk than minimun target

Changing the Target API may change some default.

But it is best practice to set the target API to the last (more recent) API
you are working with and avoid specifying a max API

the min API can be, and usually is, lower then the target API.

The javadoc, and lint tool will tell you when you use API that are not
available in lower API.

Since Android 2.2 Dalvik evaluate the existance of a method when it reach
it in it's execution the first time.

Meaning that you can do things like this:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
// use the new API
} else {
// fallback for the old API
}

If you go back before 2.2 you'll have to use Java Reflection to achieve the
same result.

Furthermore the support library greatly helps in dealing with older API and
I also use it with min version 15 cause many libraries works only with the
"support" Fragments etc.

Another way is to define different classes (fragment, activities, ...) and
play with the layout / values sdk modifier to use completely different code
for newer and older API

layout/ (default layout, compatible with min SDK)
layout-v11/ (layout used from SDK 11 and above)

as TreKing already told you you should read this link

http://android-developers.blogspot.com/2009/04/backward-compatibility-for-android.html

Re: [android-developers] Are Encrypt Opaque Binary Blobs (OBBS) supported?

[Daniele Segato]

Did you have any luck?

I created a bug here:
https://code.google.com/p/android/issues/detail?id=53039

I get this in the log when trying to mount the obb file:
10-22 17:12:56.755  166-252/? E/Vold﹕ Error loading mapping table 
(Invalid argument)
10-22 17:12:56.755  166-252/? E/Vold﹕ ASEC device mapping failed 
(Invalid argument)
10-22 17:12:56.755  166-252/? W/Vold﹕ Returning OperationFailed - no 
handler for errno 22
10-22 17:12:56.755  529-599/? E/MountService﹕ Couldn't mount OBB file: 
-1


the -dump doesn't work either as stated in the bug I created.

Anyone managed to mount an obb file?
possibly encrypted, but at present I'd be happy with an unencrypted file 
too.

Thanks
Daniele

[android-developers] Re: New OpenGL ES 2.0 Game Engine Option

[Daniele Segato]

Apparently my question has been already replied:

http://www.batterytechsdk.com/content/1089-official-linux-support
You should upgrade the homepage / doc ;)


So I move to the next question: is it compatible with Gradle and Android 
Studio?

Still there's a problem of not being able to evaluate it from Linux :) and 
probably for this reason I'll not be able to use it for the project I'm 
working on ;)

Hi,

your SDK seems interesting but I don't see support for developing in Linux.

Seems weird to me since it's easier to compile with NDK on Linux then in 
Windows (for example).

Is there a way to develop for Android on Linux using your SDK?

Re: [android-developers] What is the use of services in Android?

Hi,

I think you should tell to us what you are trying to do cause repeating 
that you do startService the second time and it "does not work" doesn't 
mean a thing if we don't know what you want to do and what your service 
does.

You probably don't want to use threads in their raw fashion

  Instead if you need background work that fits the model,
an AsyncTask is an appropriate design.

A service can run on a seperate thread if it spawns
it own thread. But if a service runs on a seprate
thread, then the method |stopService(new
Intent(getApplicationContext(),
MyService.class));| does not stop the running
service. Again this is a problem.

If we want to do some background operations, then I
think threads are better than services. Am I right?

Re: [android-developers] What is the use of services in Android?

[Daniele Segato]

Hi,

It is Upon to you to decide if you want to do startService() or 
bindService()


The meaning of startService is: wake up the service (create it if 
doesn't exist) and give it this command.


The service should know what's doing and, if the command is already 
running should just discard the new request (or whatever logic fit your 
app).


BindService say: give me a binder object to the service so that I can 
ask it directly for information.


Usually you send command with startService() and then forgot you asked 
for them.


If you want to know the state of a Service instead you bind to it.

A good practice I use when I have to show the state of some operation 
going on in background is binding to a service in the activity 
onCreate() and unbinding in onDestroy().


I define my service with a binder interface to let binded activities ask 
for informations about the state of the service (how many task are 
running, how many are pending, the progress of each one for example) and 
when I need (or when the user ask) I start a command with 
startService(). I develop the service so that it know what it is doing 
(which threads are running and doing what) so I know when to call 
stopSelf() when no more threads / operations are running.


I think Google Play app is doing something similar when showing if you 
are installing / upgrading an application.


This works very well because even if your activity die, is rotated or 
you need to know what's going on from different activities you just have 
to bind to it and ask.


Said so if you need to sync data remotely when opening your activity you 
should be using SyncAdapters

http://developer.android.com/training/sync-adapters/index.html

Daniele Segato

You've been already told by others that Services should be used to
MANAGE separate thread(s).

The important part is that while an application is used to interact
with
the user a Service has no UI and can run in background.

And with "background" I don't necessary mean off-the-main-thread.
I mean that they can run even if the application (activities) is not
used at the time.

Services have a simpler life cycle in respect to activities and they
are
not influenced or killed by the framework by changes in configurations.

Furthermore the framework will kill activities before starting to kill
services. And if the framework decide to kill your service you can
specify what you want to do with the request you received (drop it, ask
the framework to re-do it, etc...)

Services are a main component of the system and it is good practice to,
for example, use them to update underling data (better if using a
SyncAdapter) and manage remote calls.

Daniele Segato

not working correctly. No crashes, just... behaving oddly, and only

seems something bad is happening with the way that the code is being
generated. I haven't figured it out yet, but I'm digging into things
with apktool and I'm seeing a lot of differences with the generated

Proguard config that I'm feeding in is the same. Unfortunately, I
have to go back to manual builds with Eclipse for now due to this issue.

Does anyone else have any similar experiences or insight into this?
Are the Eclipse / Gradle builds using different build tools behind
the scenes which could lead to differences in the generated code and
cause some files to be mis-generated? Thank you!

Our iOS team is using NinevehGL engine: http://nineveh.gl/

Do you know of something similar for Android?

I want to add a quote from /Diney Bomfim/, the author of NinevehGL:

If you choose a 3D engine, like PowerVR, SIO2, Oolong, UDK,
Ogre and many others, you’ll be stuck inside their APIs and
their implementation of OpenGL. If you choose a third party
API just to load a 3D file, you will need to integrate the
third party class to your own implementation of OpenGL.


Another choice is to search a plugin to your 3D software to
export your objects as a .h file. The .h is just a header
file containing your 3D objects in the OpenGL array format.
Unfortunately, until today I just saw 2 plugins to do this:
One to Blender made with Phyton and another made with Pearl
and both was horribles. I never seen plugins to Maya, 3DS
Max, Cinema 4D, LightWave, XSI, ZBrush or Modo.

Which I think is true for Android too.

Do we have some option like that for Android?

*My specific need* is a library that interact well with Vuforia -
http://www.qualcomm.com/solutions/augmented-reality
<http://www.qualcomm.com/solutions/augmented-reality>
which is a library for Augmented reality using NDK and a C++
library. Vuforia examples show, via OpenGL, the camera and overlay
upon it a very simple 3D model defined in .h files.
I need something to keep all that and just change the model /
underling database of features detections.

My scouting results until now:

  * JOGL - https://jogamp.org/jogl/www/ - this is a Java library
that just act as a bind to OpenGL®, OpenCL™, OpenAL and OpenMAX
APIs inside Java - to my needs it's not that much of an help, I
only need OpenGL to show a 3D model and this library doesn't
provide a way to import one - nor has anything more then what I
can already use with NDK
  * Min3D - http://code.google.com/p/min3d/
<http://code.google.com/p/min3d/> - this is a Java library to
import OBJ, 3DS and D2D models, many guide talks about it but it
seems pretty dead project, no commit since 2011 and it use a
Scene object which somewhat collide with the way Vuforia use OpenGL
  * JPCT-AE http://www.jpct.net/jpct-ae/index.html
<http://www.jpct.net/jpct-ae/index.html> - this is another java
library which expose a very simple 3d engine and import for 3DS,
OBJ, MD2, ASC which is horribly written (IMHO) for Android
  * Assimp (Open Asset Import Library) -
http://assimp.sourceforge.net/
<http://assimp.sourceforge.net/> - this is a C/C++ library for
importing almost any 3D model around (including COLLADA and
FBX), it "just" provide methods to import the models and should
work very well - but that's no version for Android even if some
folks actually managed to use it with Android
(http://jazzyjester.wordpress.com/2013/02/02/test/
<http://jazzyjester.wordpress.com/2013/02/02/test/>)
  * Unity3D - http://unity3d.com/ - Very complete 3D crossplatform
framework, in my company we already use it, too bad you can't
integrate it very nicely with a native application that just use
3D with Vuforia in a fragment.

My current effort is aimed at trying to integrate Assimp into a
Vuforia Sample and I'll then write plain OpenGL commands to render it.

I had to study NDK, C++, OpenGL all together and this is taking a
while.[1]

 From your experience, what is the best option for an Augmented reality

If you have developed one or developed with one, please comment.

There isn't a lack of options - just looking for feedback on which ones
actually work.
The largest list I could find on this topic is this:

http://socialcompare.com/en/comparison/augmented-reality-sdks

I probably need:

  * GPS and sensors use
  * Placement of markers, icons, and some vectors (lines or shapes) in
the 3D world.
  * Should work without internet or data. Shouldn't be a problem since I
am not counting on an online feed.
  * Non GPL.

I may need ( in the dream future):

  * more complex 3d rendering with meshes and dynamically loaded
textures. Nothing too major, just maybe like overlaying a Google
Earth like image with the camera. ;)

I probably don't need:

  * Data for the Points of Interest, I'll provide my own and they'll be
small in number.
  * Computer Vision based reality. That eliminates quite a few.
  * Object manipulation - I don't need to design cities or anything like
that.

I'm looking for more of the viewfinder sort of thing.

I prefer buy over build, I think because I don't want to start from
scratch on working around the bugs on every single device. Of course, I
don't want to buy and still have to fix all the bugs myself.

So here are some I'm considering.

  * ARLab.com. As described on their website at least, it sounds like
the ArBrowser


don't know anything about this, can't comment on it


  * Wikitude. A bit more expensive, but possibly more established and
mature. Since their sample app has a million downloads.


this one sucks in my opinion.
It use a webview for an HTML5 app.
HTML5 app sucks for many reasons. Performance is one of them.
I would stay away from it.


  * http://www.chupamobile.com/products/details/296/Augmented+Reality+Toolkit/.
Probably made by a guy in his basement, but if it does work, it is
only $20. Probably worth buying just to prototype something before
going full scale.


As for ARLab, don't know, can't comment

Reading seems like Metaio http://www.metaio.com/ is the most complete 
(cross platform) Augmented Reality framework.
But you can't develop for it on Linux which makes no sense at all in my 
opinion.



In my company we use Vuforia 
http://www.qualcomm.com/solutions/augmented-reality for natural features 
and markers tracking.

It's unbelievably fast and reliable.
We haven't much experience with it on Android yet (we are starting now 
on the platform) - but I personally tried the examples and it works 
pretty well, fail to run only on very old devices or low end devices, I 
also tried with a RAZR with x86 processor and it works... MIPS devices 
will not work.
it doesn't provide a 3D engine tough (see my other post in this ml) so 
you'll have to find one on your own.

I read about services in Android very carefully, but I didn't find any
valid reasons to use it. E.g.

 1.

By default services run in the main thread, which most of the
applications don't want.

 2.

A service can run on a seperate thread if it spawns it own thread.
But if a service runs on a seprate thread, then the method
|stopService(new Intent(getApplicationContext(),
MyService.class));| does not stop the running service. Again this is
a problem.

If we want to do some background operations, then I think threads are
better than services. Am I right?


You've been already told by others that Services should be used to 
MANAGE separate thread(s).


The important part is that while an application is used to interact with 
the user a Service has no UI and can run in background.


And with "background" I don't necessary mean off-the-main-thread.
I mean that they can run even if the application (activities) is not 
used at the time.


Services have a simpler life cycle in respect to activities and they are 
not influenced or killed by the framework by changes in configurations.


Furthermore the framework will kill activities before starting to kill 
services. And if the framework decide to kill your service you can 
specify what you want to do with the request you received (drop it, ask 
the framework to re-do it, etc...)


Services are a main component of the system and it is good practice to, 
for example, use them to update underling data (better if using a 
SyncAdapter) and manage remote calls.

[android-developers] 3D model importer / engine for Android / Android NDK for use with Vuforia - what do you use?

[Daniele Segato]

Hi,

I'm scouting for a 3D model importer library.
I'd like it to have support for COLLADA and FBX format.

Our iOS team is using NinevehGL engine: http://nineveh.gl/
which is just perfect... but for iOS only.

Do you know of something similar for Android?

I want to add a quote from *Diney Bomfim*, the author of NinevehGL:

Re: [android-developers] Dealing with 1000's of different devices, each one with its own bugs

[Daniele Segato]

Hi Thomas,

The bug trackers I proposed are all free to use and cloud bug trackers 
(meaning no one has to maintain a server or something).


What's needed are admins for that bug tracker.
Categories can be created when needed.

If there are enough maintainers I think it can be done, the community is 
big and if people really care about this issue I don't think it should 
be a problem to find some.


If they don't really care so much then we will see no one stepping in, 
that's for sure.

on the one hand that's a good idea. On the other hand we would need
someone who is willing to host and maintain that bug tracker. Setting up

That's why I think that a wiki has more chances to "take off" with the
majority of Android developers as users. There are 10.000-something
different Android devices out there. It's not much of a problem to
introduce new devices in a wiki. But it takes a whole deal of dedication
for doing that in a bug tracking system

I think we need a bug tracker that allow tagging by vendor, devices,
device variant, android version and let the user combine those when
searching.
It would also be good to have some statistics on those tags/categories.

Jira would be perfect, but it's not free.


I can list some, but do not know them well enough to compare or to know
if they fit:

- Google Code: https://code.google.com/
- GitHub - the repository can just be a readme - https://github.com/
- SourceForge - http://sourceforge.net/


I'm sure there are others.

We can bring Google's attetntion at this problem but we should be

devices..They would only be able to download 4-5 apps (just saying...)...



That would be absolutely perfect.
What do you think an user able to download 4-5 apps of that device?

What will the reviews say about it?
--> don't buy it
What will the vendor producing that device do with next devices?
--> be more complain to the standards.

But hey, that's was just a suggestion on what one can do knowing the

 use a bug tracker to grow a bug database about

I know, I just used the term Fragmentation because that's the term Omer

So it's not about fragmentation, except for in the latter sense.

I also disagree that starting an issue database will help anyone.
Telling developers to worry about 900 bugs their app may need to worry

By the way - read the original post - I am NOT talking about official

Not screen sizes, API levels features and so on.
I'm talking about BUGS.


I got it.
I'm just saying I never hit one.
I wrote that message with the specific intent of moving this discussion 
on facts in opposition to "my opinion VS your opinion"


I never said the API are flawless (as Piren pointed out in the other 
response to my message). It's their implementation that may be buggy.


I said my perceiving of the issue is not so bad as you pictured it. 
Maybe 20% of the time for a project may go for fragmentation (both bugs 
and handling API changes, screen sizes etc.).
I do not often write with native code, Graphics, Bluetooth, Sensors etc. 
Sure, my user bay may not be so big too, sure.


But you know what? I think it's more constructive to list issues and 
try, together as a community, to route them out instead of just wining 
about fragmentation.
Complaining with Google doesn't help either, because they can't do 
anything about a bug created by someone else.


The only thing you, and all the other hitting this kind of issues can do 
is find a way to list them out. If you really care about the issue you 
should discuss that and put facts (as this list) in front of claims 
(fragmentation sucks).




All the issues below were tested with a device in front of me, these are
not just assumptions.
Ok, let's go:

1. On Samsung Galaxy S and most of its variants, when you use this
simple and documented intent:
http://developer.android.com/guide/topics/media/camera.html#intent-image

The camera app behaves completely differently, and will sometimes ignore
MediaStore.EXTRA_OUTPUT.
If you run the same code that would work on any other device, most
likely you'll crash on a NullPointer, unless you workaround for Samsung.
Tested with the device in

2. The API AudioManager.setMicrophoneMute
(http://developer.android.com/reference/android/media/AudioManager.html#setMicrophoneMute(boolean))
  doesn't work at all on some Motorola devices (Milestone variants).
It will literally do nothing, not mute the mic and even tell that you
DID mute the mic (isMicrophoneMute will return true after that).

3. Using a GLSL shader with 4x3 matrix multiplication containing some
0's on Galaxy S4 will miscalculate the result, and produce artifacts
because of that.
Every other device does the same calculation fine, except S4.

4. Using camera preview on some Sony Xperia variants
(http://developer.android.com/reference/android/hardware/Camera.html#setPreviewCallback(android.hardware.Camera.PreviewCallback))
will give you flipped or even cut preview frames - so it's completely
useless for implementing video calling on these devices.

5. Reading from the proximity sensor on Motorola Milestone variants
(http://developer.android.com/reference/android/hardware/Sensor.html#TYPE_PROXIMITY)
will give you completely unrelated values, different from every other
device and ignoring the sensor specification (getMaximumRange() and so on).

6. Running a GLSL shader with 8 varying vectors (the minimum of
available varying vectors according to the spec., that should be

instantly.

7. Using an Intent to pick an image from the gallery
(http://stackoverflow.com/questions/5309190/android-pick-images-from-gallery)
on some Galaxy S variants will cause the Gallery app to crash.


That's just the ones that came to my mind right now.
I'm sure this can turn into a whole book when other people contribute.


Thank you for this list.

I ask you to avoid the flame and start a constructive discussion instead 
about what we can do, as a community, to help other developers discover 
this kind of issues.


A issue database is what we need.

I don't have the resources to put one up. Probably none of you, alone, 
has them.

Re: [android-developers] Dealing with 1000's of different devices, each one with its own bugs

years, and to be honest, I'm fed up with it
.I've decided to move to iOS development, and the only way to convince

fragmentation


[snip]


To make it clear, I'm not talking about "official" fragmentation.
I don't talk about different screen sizes, densities, features, OS
versions and so on.
I talk about the "unofficial" fragmentation. The fact that most devices,
even the popular ones from the big companies like Samsung, HTC,
Motorola, LG and so on, contain tons of implementation bugs that prevent
apps from working correctly.
I'm talking about the fact that you can call a certain simple API, test
it on a stock Android ROM (like on Nexus 4), and then have your
application crash on some Samsung, that decided to break the
implementation because of some customization.

How can people stand that?
How is it possible to write code, when the machine that executes it is
completely broken in unexpected ways?


[snip]

I feel a little put off by this.

Never had issues like the one you describe when doing the things are 
they are supposed to be done (following the docs and guide lines).


When someone talk about fragmentation in Android I laugh. Seriously.
in iOS if you want to support different device you literary has to 
develop twice. True, they do not have has many devices. But Android is 
designed from the ground to support the fragmentation:
- you can address different API with just an if in your browser or using 
-v14 in your resources/layouts/values
- You have fragment and the support library bring backs most of the 
features you need for supporting old devices


Reading your message and the replies you get it seems like everybody is 
experiencing bug in how the API is implemented.


I don't trust you.
What I think is that either I am be always very lucky either you did 
something wrong.


I'm open to change my mind, but I'd like to have some practical example, 
you seems to have many since you spend most of the time fixing them.


Why don't you share what they are? Maybe you'll discover you are doing 
something you shouldn't or if you are right it could be a start for 
other developers to have a list of gotchas and issues you have to be 
aware off making life easier for everyone.

If you ever find a way: you found a bug

Whatever you are doing: don't. You are doing it utterly wrong.

As I user, if I click home or the app switcher that's because I want to 
go home or switch app and thus want your app to go in background.


If I'll ever found an app that doesn't let me do that I'll uninstall it

We don't need your app on the market.

I guess don't use an Android phone and never tried to read the design

Stop writing code and take your time to do that. Do it now before you 
waste any more of your (and users) time.

Re: [android-developers] Why doesn't the ADT show me the javadoc for a class in android.jar when I have the javadoc path set for the jar?

[Daniele Segato]

On 01/02/2012 07:21 AM, David Karr wrote:

This may be completely Eclipse-specific, but perhaps not.

I find it's very inconsistent whether I can get Eclipse to show me the
Javadoc for an Android class or method, even when I appear to have valid
javadoc attached to the "android.jar" file.

For instance, right now I'm viewing a class in a sample application that
references SQLiteDatabase. There are no compile errors, so I have all of
my dependencies properly set. I hover on the class name reference and
force the javadoc to display, it prints the class name as
"android.database.sqlite.SQLiteDatabase", but it says "Note: This
element has no attached source and the Javadoc could not be found in the
attached Javadoc.".

I then went into the Project Explorer and expanded the "Android 2.3.3"
library, exposing the "android.jar" file. I right-clicked on that and
selected Properties. I clicked on "Javadoc Location". It's currently set
to "Javadoc URL" and the "Javadoc location path" was set to the path to
the "reference" directory in the android SDK. I clicked "Validate" and
it said "Location is likely valid".

Just in case, I verified that
"android/database/sqlite/SQLiteDatabase.html" exists at the root of the
javadoc tree.

So why is it not showing the javadoc for this class?


Hi,

I faced the exact same issue...

it comes down to the fact that Eclipse assume the sources will be always 
more reliable of the javadoc.


Actually I would think the opposite since the source may contain 
auto-generated content or, like in the android case, be integrated with 
additional metadata (the SDK version a function has been introduced).


Shame Eclipse for that.

I discussed a lot in the #eclipse channel on freenode (IRC).. They 
insist Google is doing something out of specification by adding data to 
the javadoc (that's the attitude they have).


I opened this bug:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=366811

It has been closed after a short while by setting it duplicate of this one:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=178071

it's opened since 2007 (sic!) and it's currently marked as "helpwanted"

I remember opening the same issue to android bug tracker but can't find 
it anymore :/



If you happen to have some news or workaround I'll be happy to know

why don't you just go into debug mode and see where the bmp goes null?

I never actually tried but I think that if you target a later version 
(say Android 4.0.3) you can define your resources, layouts and so on 
with the 4.0.3 specification, that allow you dpi differentiation.


Device that don't support it should just ignore them.

As I told you, I never tried but I would be surprised if it doesn't work 
this way.



and the Galaxy note is 2.3.5 I believe.


if my supposition is right the Galaxy note will ignore the dpi

[android-developers] Multiple On-Going Notification with progress bar keep changing position

[Daniele Segato]

Hi,

I have this exact same problem: 
http://stackoverflow.com/questions/6189817/pin-notification-to-top-of-notification-area



The on-going notification shown the download progress..

I need to update those notifications periodically, every 3 seconds now: 
I upgrade the progress bar and text informations.


When more then one file is being downloaded every time I refresh the 
notifications they switch places for a split second.



I'm using an unique ID for each download when notifying.

Is there a way to tell Android "do NOT change position of my 
notification, just update it's content"?


a snipped of code

Notification notification = new Notification();
notification.icon = R.drawable.ic_menu_notification;

// I tried with same when for every notification, no luck
notification.when = when;
notification.contentView = new RemoteViews(context.getPackageName(),
R.layout.download_notification);
notification.flags |= Notification.FLAG_ONGOING_EVENT;

notification.contentView.setTextViewText(R.id.download_notification_status,
notificationStatusText);
notification.contentView.setProgressBar(R.id.download_notification_progress,
1, (int) (progress * 100.0f), false);

notificationManager.notify(downloadId, notification);



When I execute this for 2 download A and B I can see them switch 
position in the status bar, when it happen on 2 is annoying, when you 
are 3/4 download running it really sucks :/



I simplified the code for the sake of the example, I removed the Intent 
part which is not related I think.




Thanks,
Daniele

I gave a way to do it which is independant of the development environment.

actually a single command could have been enough:

sed -i 's#old.package.name#new.package.name#g' `grep -Rl 
'old.package.name' *`



but if you have a very simple package or colliding packages that may 
have had issues.


Hopefully we are developer and are not scared of the command line and/or

Let's say you have an Android game.  You want to duplicate the project

to be trivial.



it should be easily done with some unix shell command:

1. copy the project

# now move the directory
2. mv src/old/package/position src/new/package/position

# change the "package" inside java sources
3. sed -i 's#^package old\.package\.position#package 
new.package.position#' `grep -Rl '^package old\.package\.position' src/*`


# change the imports inside java sources
4. sed -i 's#^import old\.package\.position#import 
new\.package\.position#' `grep -Rl '^package old\.package\.position' src/*`


# if you have defined custom view change the tags
5. sed -i 's#<\(\/?\)old\.package\.position#<\1new\.package\.position#g' 
`grep -Rl 'old\.package\.position' res/layout*/*`


6. finally manually fix your manifest, or using a command like the one above


I also suggest to use a versioning tool like git and check the diff at 
each step, committing if it's correct or resetting/cleaning if you did a 
mistake... at the end you can squash the commits to be a single one with 
rebase interactive or if you rename the package on a branch (suggested) 
just merge your branch with the --squash option back in mainline


if you still don't know them run learn regex and unix shell :)

on a mac (or bsd) the above sed commands should be rewritten with:

sed -i '' 's###'

note the double quote after -i

if you are on Windows well... :) enjoy doing it manually with Eclipse, 
it may help you a little but it will take you some time and probably 
some head ache ;)

[android-developers] Notification status bar custom layout, guide lines are wrong?!? (primary color)

[Daniele Segato]

I was following this guide lines:

http://developer.android.com/guide/topics/ui/notifiers/notifications.html#CustomExpandedView


which states:


"[...] to use the standard text colors on versions of Android lower than 
2.3, you should use the following styles for res/values/styles.xml:"





  ?android:attr/textColorPrimary


  ?android:attr/textColorPrimary
  bold







Which produce a White color on a light gray background on the Android 
2.1 and Android 2.2 emulator... It's obviously very hard to read...


Should I ignore this guide lines?

anyone sharing experiences about this?


ps: The secondary color is fine, but I need the primary too...

[android-developers] How do I preserve selection and/or checked items in a ListView after device rotation?

[Daniele Segato]

The ListView save in its internal state the checked items and restore
them.

It restore them after the device is rotated.

But then clear them out when I set it a new adapter (which, in my
case, extract exactly the same data).


I'm using a ListFragment with compatibility support package v4 and a
Loader to get a custom CursorAdapter.

When the loader give me the adapter I call setListAdapter that clear
out the checked, restored, state.

never mind...

I just had to set the adapter onCreate instead of setting it up on
loader complete.
