[android-developers] How Android LVL react when one or more gmail accounts are logged in

[janvi]

Hello all
 
   I need some clarification on how android LVL will react when multiple 
gmail accounts are logged in the phone i,e one of the account may be valid 
account(account through which app was purchased) and other may be normal 
gmail accounts
 
Will it actually validate the license check even phone has multiple 
accounts???
 
According to my knowledge it considers very first gmail account added to 
the phone and sends the appropriate response if app was purchsed through 
that account
 
Please correct me if iam wrong
 
waitng for some more info from you all

Re: [android-developers] Re: Best approach to handle Catch-Exception

[Luiz Henrique]

Hi Lew,

I agree with you and because that I'm spending a lot of time looking for
the best solution to handler my exceptions in my android application. If
you didn't understand this way, sorry.

We have dozen of different technics to handle exceptions in a java
application, AOP is just one them
http://janistoolbox.typepad.com/blog/2009/12/errorhandlingaop.html

The point is not if exceptions are important or not, particularly for me
are very important for a success in a application (but it doesn't matter).
So, this is my first android application and I just would like to heard and
share some knowledge about usually how the guys handle your exceptions.

Just that.

ACRA is an awesome report bug solution to handle uncaught exceptions  (100%
free).

Cheers,
Luiz

create a ContentProvider (in my case VideoProvider) and override 
openAssetFile like this:
@Override
public AssetFileDescriptor openAssetFile(Uri uri, String mode) throws 
FileNotFoundException {
Log,d(TAG, "uri: " + uri.getPath());
AssetFileDescriptor fd = null;
try {
fd = getContext().getAssets().openFd(uri.getPath().substring(1));
} catch (IOException e) {
e.printStackTrace();
}
return fd;
}

in AndroidManifest add:



if you want external app to access it i think you could do it be creating 
an Intent like this:

Uri movieUri = Uri.parse("content://your.package.videoprovider/movie.mp4")
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(movieUrl, "video/*");
startActivity(intent);

where movie.mp4 sits in assets/movie.mp4

Alex, I am having the same problem accessing resources through a content

The weird thing is it workd from within the main app, but not passing a

Why would you call that code "dirty"?

Is code that handles bad conditions somehow inferior to code that handles 
the happy path?
I'm inclined to think the exact opposite.

Much more likely to be good engineering than "interceptors/AOP" (huh?) 
would be good refactoring 
of your code. Dealing with exceptions is not an Android issue but a 
programming issue, and you 
need to fully understand what exceptions are and how they fit strategically.

The boilerplate for exceptions can be verbose, but hey, at least you don't 
actually have to work 
for a living. The worst you can fear from it is a slight increase in 
callous on your fingertips.

You reduce verbosity by isolating checked-exception handling to the 
lower-level routines. One 
standard (not necessarily best-practice) technique is to rethrow as a 
custom exception (checked 
or unchecked) which is handled by the top controller level in a 
user-friendly way. The lower-level
routines do something pretty specific, say, open a resource, and eat all 
the checked exceptions 
that might engender, replacing them with defaults, custom exceptions or 
navigation, error return 
values, or whatever your strategy dictates. 

By relegating verbose exception handling to lower-level routines, the 
higher-level ones read 
much more like happy-path laconic self-documenting scripts.

What do you mean by "others applications"?

Re: [android-developers] Re: Best approach to handle Catch-Exception

[Luiz Henrique]

Hi Nobu,

we are sharing the same ideas about how and in what kind of condition
should be showed error messages. Btw, I'm using ACRA to handle uncaught
exception and it have worked fine.

About catch-exception you understand me well. So, nowadays I'm using
try/catch to grab the exceptions and sometimes there is a bunch of "dirty"
code just to handle exceptions. I would like to know is there is some
approach in android to handle in an unique Class/Method catch-exceptions.
For example, something we can do using interceptors/AOP for others
applications?

I hope that I have been clear in my placements ;)

Cheers,
Luiz

[android-developers] Re: Best approach to handle Catch-Exception

[Nobu Games]

If I understand you correctly, you should proceed like with any other 
application. Which is: propagate errors to the GUI in order to make the 
user aware of the problem. But only under following conditions:

* The user expects an immediate result but the action failed
* The app cannot recover from that problem and requires the user's 
attention (like activating GPS, inserting SD card, corrupt / unformatted SD 
card etc.)

If it is something the app can automatically recover from, do not bother 
the user at all. Typical scenarios are failed synchronization / download / 
upload attempts. Even in severe cases like data loss, if your app is able 
to fully restore the data "from the cloud" or a local backup I would not 
bother the user at all with these details. Stay silent and create a smooth 
and painless user experience.

Most users are not interested in (problem) details anyway and they'd click 
away your notifications without reading them.

You also should silently log all errors into a file. Provide a "support" 
feature that attaches the log file to an email. It's also a good idea to 
override the uncaught exception handler in order to log uncaught exceptions 
(but don't forget to invoke the default handler after logging, otherwise 
you won't get the "app crash" dialog).

on the native heap but they counted against the Dalvik heap's usage (which
is why you would get OOM anyway.)

As of 3.0 Bitmaps are allocated on Dalvik's heap.

Re: [android-developers] OOM with heap enough

[b0b]

Bitmap data is not allocated in the Java heap but in a much smaller area of 
native memory.

So you can have several MB of Java Heap free and still have Bitmap OOM.

Bitmaps are a total PITA to manage with Android. But it's doable.
Except that when you thnk you are done fixing all OOM, a new surprise 
always awaits you.

Re: [android-developers] SurfaceView

[Romain Guy]

Surfaces are always hardware accelerated in the sense that we use the GPU
and/or other hardware chips to composite them on screen. This means all
windows on Android behave this way. If you use a Canvas on a SurfaceView,
the Canvas itself will still perform software rendering.

Re: [android-developers] Windows 8

You should ask Microsoft about that, thought.

Anyway I do not know what you understand for a decent PC. If it is a 
laptop, you are likely to be forced to use the SO that the manufactured 
have said, but if it is a PC box, it its really easy to buy one without 
SO at all and install it by yourself.

Re: [android-developers] SurfaceView

According to Mario Zechner's book "Beginning Android Games", you need a 
SurfaceView so you can render from a thread different from the UI one, 
and also because the Surface may be hardware accelerated.

[android-developers] Re: ListView checked state wrongly shared between 2 views when reorienting screen

[João Paulo Forny]

Sorry for asking it here, but i have the same problem and some points were 
not clear for me. 

What do you mean by views that don't need to save their state? In my case, 
the problem is with custom views that don't have the same ids, but its 
children do, because it is created from a xml file. I thought of many 
workarounds, like using android:configChanges attribute in the manifest or 
commenting the line that calls the super.onRestoreInstanceState(), but I 
really wanna know if there is a solution for this that is not considered a 
workaround.

Thanks in advance,

Re: [android-developers] SurfaceView

[Romain Guy]

The main reason to use a SurfaceView is that you control the rendering
thread and you can eliminate a lot of overhead. Views must use the
invalidation mechanism to trigger redraws. A call to invalidate() walks up
the View tree and marks Views dirty on top of keeping track of some extra
state. When it reaches the top of the tree, it schedules a draw pass, which
will in turn traverse the View tree down to call View.draw() on dirty Views
(and also manage some extra state.) All this is usually unnecessary when
you write a game.

With SurfaceView you can draw directly.

Re: [android-developers] OOM with heap enough

[Piren]

I remember reading about a similar issue in the past and experienced the 
same issue as well.
>From what i recall, but dont take my word for it, even if there is room in

heap can be enlarged to include the needed space, instead of trying to use

Since you're already at 48MB, you've just pushed through the limit with the 
new needed allocation (regardless of the fact you have the space), and 
Dalvik throws the OutOfMemoryException.  I had it happen to me as well. 

Only solution i've found? to never get the heap so large it sits on the 
edge (stupid bug, stupid solution, i know).

I think Dianne Hackburn mentioned that, maybe a google search will find it.

Re: [android-developers] Re: OOM with heap enough

[Francisco Marzoa]

As told to Mark, I do not think so: the game is just starting, loading 
the first Screen at all. Also I have never experienced such problems on 
my own devices or emulators, and I have spent many time watching DDMS... 
of course it cannot be discarded at 100%, though.

Well, it may happen, but the evidence on that is really weak. The game 
has just started and it is loading the main menu screen, with only a few 
objects in memory, so it is unlikely that in these circunstances and 
with 15Mb of free heap an image of just 1M5 as raw ARGB_ will not 
find an slot.

There was no new SDK for Android 4.0.4, and hence no new official

the AOSP sources for 4.0.4, and that this is available for download,
but it will not be through the SDK Manager.

That's exactly what I write down in my Google+ profile this weekend, so 
I fuuullyy gre with that. ;-)
I was faced with similar heap issues, did the same thing as you did, 
mostly came to the conclusion that the best thing is just to drop the 
bitmaps altogether or reduce their resolutions as much as possible.
You should watch out with Recycling manually as this might cause 
issues in some instances (like when the bitmap is used in a listview), 
i found that just nulling the drawable Callback and making the bitmap 
Purgable was sufficient for GC to work correctly and avoid OutOfMemory 
exceptions.
I did it manually to reduce heap consumption peaks. You know: sometimes 
I need to load different bitmaps for a given screen, but even when the 
object of the previous screen has been already dereferenced, the bitmaps 
it uses has not yet been collected, so by a second I will have bitmaps 
for both screens on the memory. I have noticed that if I recycle the 
bitmaps of the first screen before switching, when I load those needed 
for the second screen the old ones have yet been recycled, thus my heap 
use peak is a lot of lower.


Of course you should be careful on not using recycled bitmaps and things 
like that, but my code is pretty clear and I am not experiencing this 
kind of crashes at all, so there is no point worrying about... we have 
enough to be concerned with actual bugs to think about potential ones... ;-)
When it comes to testing, you can always just use your more 
knowledgeable customers as QA.
I have no doubt that if you develop apps like developers tools or so 
this could be very useful, but I do casual games and most of my users 
does not even fill crash reports, and the few ones whose do put things 
so descriptive as "it is not working", and others simply comply on 
comments rating the game with one star and swearing about my mum or so...
Start a beta program with a bunch of users (or friends :) ) that will 
test your app in advance.
That's a great idea that I have had in mind before, but discarded due as 
typical nerd I have not many friends... X-D


But perhaps I could think about any incentive. I will have it in account...
You'll be able to reach a wider variety of devices and catch those big 
issues early on before releasing the app to the public.


Emulators by the way, wont do the job as they dont emulate the 
different hardware specifications of each device.
Well, it is true that they have great limitations, not only for not 
having the hardware, also because some manufactures make their own 
customized Android versions. But they are still useful for testing and 
detecting obvious bugs.


Hope there were a "renting mobile" service on my town or something 
similar...

[android-developers] ICS 4.0.4 emulator image?

I have problems with some devices that uses ICS 4.0.4, mainly with 
Samsung Galaxy SIII ones. I have create an emulator instance to try to 
debug this as closed as possible to SGS3, but I have been unable to 
reproduce the problem at all. I only have ICS 4.0.3 on the emulator that

you can't add the same view to two viewgroups at the same time.
if you want two lists, you'll have to initialize and set two lists.

[android-developers] WebView - Flash overlap issues in Android

[James]

platform: ARM7 based device
android version: ICS4.0
browser: android default browser

I am testing flash websites on android browser and observing that flash is 
always overlapping over webview. So if any website contains any list 
view/menu which falls above flash, always goes behind the flash with 
android browser.

Below are the suggestions which I have tried already,
Override surfaceview add in WebView to change the zorder to false; 
(setZOrderOnTop(false)) 
Changing html page setting to opaque or transparent
I have seen this working on GalaxyS2 & with Google TV image (with Chrome 
browser) on same platform.
In Chrome browser (GTV), WebKit rendering is done on above SurfaceView and 
for Flash Video's it is using PluginWindow. So WebView always remains on 
top of all other window. So no problem.
Interesting thing is, I have not found a single web reference which tells 
the possibility of rendering Webpage over SurfaceView and there is no 
reference about PluginWindow in android.

Quick suggestion/help required.

Re: [android-developers] debugging crashes on some systems ( not all )

[Francisco Marzoa]

Hi,

This is one of the worst things of Android development ever. I am facing
similar problems, also most of them with SGSIII, getting OOM crashes with
no apparent reason. I have run the app in several different actual devices,
also different emulator instances, one of them trying to fit as closed as
possible the SGSIII settings. I have reduced heap consumption to the
minimal, but I am still getting these annoying errors.

Now I am considering to buy an SGSIII actual device to test it, but this is
not an option in most of the cases, and it is not clear if this will solve
this problem -may be only some SGSIII are affected, and the one I bought is
not one of them-.

I released a new version of my app last Friday with disastrous results due
to this problem -thousands of uninstalls-. I have did my best since them
improving a lot memory use, writting code for actively recycle bitmaps when
they are not needed and thinks like that, with excellent results (in an
emulator instance with same resolution, density and VM heap budget than
SGS3, I got now a 40% less of peak memory consumption than before). And it
is really frustrating to see that crashes continues after all that effort.

We need "something" to fight these problems.

Bests,

Re: [android-developers] Digest for android-developers@googlegroups.com - 25 Messages in 19 Topics

[avinash shyam]

hi,
 how  to click on a button after rotation animation in devices starting
from level 9?
Its a menu of 5items which opens up like cards in our hands and clicking on
it after animation should do somethings.
It sounds easy but i am having trouble as the the click happens on the
original poition and not at the position after the animation.
i have used the XML for the animation part, and setfill(true) which causes
the images to stay at new positions after animation but its not clickable
in the new positions.

Please help.

Try using this code inside your Activity. The finalContent will be the

Generally no, because generally phones are not FM radios. *Specific*
phones might have an FM radio chip, and those *specific* manufacturers
might offer an API for working with those chips. You are welcome to
contact such manufacturers to find out.

Re: [android-developers] hi friends

[Michael Banzon]

First: I'm betting that you won't find anyone willing to give you a
complete solution to this very vague problem. If you can ask a more
specific question based on a real problem - not easily solvable by
searching google etc. - people will be more likely to provide you with
useful help.

Second: You really need to consider that the security in your application
is based on server communication. Several issues come to mind, including
connection issues and the fact that it seems that the app contains the
secured information which isn't quite good practice (for issues like
preventing large downloads etc. you could provide a decryption key).

+1 to that.  Personnaly I was interested in MediaPlayer logcat output to 
troubleshoot issues. Some debug info is only available in the logcatand 
having no easy way 
for a user to send it for debugging purpose is a real pain: "It doesn't

It wouldn't be much of a setting if it still allowed apps to get the
location, now would it? =P

You can use getLastKnownLocation(), but obviously that could be very old
and useless.

[android-developers] Retrieving GPS coordinates when location services are not enabled

[Android Test]

Hi All,

Assuming the device's "Use Wireless networks" and "Use GPS satellites" 
settings under Location is not enabled, is it possible to still retrieve 
the location coordinates.

Currently, the best is to redirect the user to the settings page is not 
enabled. I find this disruptive as needs to navigate away from the app.

If i am not mistaken, you can enable the settings programmatically (Am I 
correct?).

I don't need the exact coordinates, is it possible to get the cell tower ID 
without the settings enabled?

Thanks In Advance

[android-developers] How to create soap request in ksoap2 for a wcf webservice method with complex types?

[Raneez]

I have successfully accessed web services using ksoap2 but i am stuck with 
calling a web service method with data contracts.

The webservice request in SoapUI is shown as :

http://schemas.xmlsoap.org/soap/envelope/"; 
xmlns:tem="http://tempuri.org/";   
xmlns:pat="http://schemas.datacontract.org/2004/07/Patient_Service.App_Code.Common";>
  
 
?
?
?
?
  
   
 

The arguments ID,Name,Age and Address have different namespaces

Here is the code i used to create the request:

request=new SoapObject(NAMESPACE,"PatientLookups");SoapObject sub_element=new 
SoapObject(NAMESPACE, "oBenefitsandEligibilityEntity");


for(Map.Entry entry: properties.entrySet())
{
PropertyInfo pi=new PropertyInfo();
pi.setNamespace(entityNameSpace);
pi.setName(entry.getKey());
pi.setValue(entry.getValue());

sub_element.addProperty(pi);

}
request.addSoapObject(sub_element);

but i get this exception in logcat:

 SoapFault - faultcode: 'a:DeserializationFailed' faultstring: 'The formatter 
threw an 
 exception while trying to deserialize the message: There was an error while 
trying to

[android-developers] Re: HttpUrlConnection no print data to my screen

[Piren]

 - Thats not a good way to read a stream. look up on how to use buffers
 - Its a horrible idea to perform findViewById in a loop. you should only 
do it once before the loop.
 - never do long processes on the main thread. especially not network 
access. look up how to background tasks in android
 - setText replaces the entire text with the new value. seems more likely 
you'll want to collect all the input before you set it to the view or at 
least concat it instead of replacing it.

[android-developers] Re: debugging crashes on some systems ( not all )

[Piren]

When an app crashes the user has an option to send a report, you can use 
your dev console to read the crashes and see what happened. You can also 
use external services like Bugsense to help you out.

Regardless of that, it's always a good idea to have your own test version 
with as many logs as possible and a mechanism to deliver them to you, then 
send that version to the users that are having difficulties

Re: [android-developers] Disabling DisplayList creation by Views

[hanni]

Hi, thanks for the quick response!

You are right, of course. The DisplayList was simply holding references to 
some Bitmaps that were also referred by my custom View elsewhere.

The Eclipse Memory Analyzer Tool is a bit more difficult to use with 
Bitmaps, after DisplayLists were added. When checking the Retained Heap 
size of a View, the value supplied will typically be too low, because 
DisplayLists have grabbed some of the Bitmap references. The DisplayList is 
then considered by MAT to be the main holder of those Bitmap references, 
because it's closer to the GC root.

Thanks

[android-developers] Re: Beginner question on layouts

you should really read the documentation and do the plethora of tutorials

Regarding the textview, that's what String Formatting is for (%.2f), look 
it up.
