Trying to find Android App ANR reason - android

Has anyone had an issue where their Android app has gone ANR when being resumed from background with the main thread getting stuck at:
at android.view.GLES20Canvas.nFinish(Native Method)
It seems to happen to me after sending the app to the background multiple times, after drilling down between 3 to 4 activities on the stack then going back up to the root activity multiple times.
Here is a complete stack on main thread before ANR:

I have just confirmed that I can not recreate this bug on a device Acer 100 7" Tablet running android 4.0.3
My other test device Nexus 4 running android 4.3 recreates this bug with certainty on around the third time resuming the app after opening 3 or more activities on the activity stack with in application.
Weirdness. Also seeing it on an HTC running 4.4

I got this error report from crashlytics. Please help me to find out.
there is issue of the layout resolution,i have faced these kind of issue many times, better create folder structure as given bellow
layout-large
layout-small
layout-medium
I found the issue:
I just created different folders for landscape and portrait
e.g ->
layout-land
layout-port
But in Androidmanifest file i set the orientation as landscape.
Once i call intent for this activity and press power button and rotate the screen app crash and got this exception.
I don't know what is happening but i guess when the screen rotating it searches the xml file in layout-land and layout-port.

I got it a few times on Android 4.1 devices when the app is coming back from the background.
You get this only on 4.1v?
Seems that your rootview or your windows is unavailable, we need more coder/log info to get better results.
If so, there isn't a bug, you need to check for your views not null, maybe the GC has quit your view so you get this error.
Please tell us more info, when happens, frequently?, how many time has pass from background?, and so on

GCM issues on the android client

I have an android app that was working previously, I had to set up the dev environment on a new PC. Everything compiles fine (i'm using Android Studio), but I get the following error:

It's saying it cannot find gcm.jar which is clearly in the project and in a folder called libs. These were the common issues that people reported in other SO posts. The app basically launches and then crashes on the spot... But i'm confused as the setup is correct.
Is there anything else that could be wrong with this?
It might be a build.gradle issue. You should have this in your build.gradle file
dependencies {
compile files('libs/gcm.jar')
}
Once you've added that, go to Tools -> Android -> Sync Project with Gradle Files

Unable to start activity On Sony Experia S

I recently published my app to the android play store.
I see a whole lot of error logs from one device in particular. It's a Sony Experia S.
I contacted the owner of the device, and he says he has the latest version of android ( don't know the exact version ).
I heard from a colluege developer that there are more known issieus with sony devices and android.
This app in particular works with fragments... Don't know if this is the problem but... Maybe the sony's don't know how to cope with them.
Does anyone have an idea what this problem could be.
Error logs looks like:
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.crosscommunications.kvodeventer/com.crosscommunications.kvodeventer.KVODeventerActivity}: java.lang.RuntimeException: Unable to start activity ComponentInfo{com.crosscommunications.kvodeventer/com.crosscommunications.kvodeventer.TabControllerHome}: java.lang.NullPointerException

Thnx
Just put a null check to your code:
KVOHome Acvitivity, line 52.
at com.crosscommunications.kvodeventer.KVOHome.onCreateView(KVOHome.java:52)
Most probably, Sony sends a null value to your code.

NullPointer exception at android.support.v4.app.FragmentManagerImpl.makeInactive

I'm seeing a weird exception in Android Support Library - the stack trace is below. Any ideas what could be causing this? I'm unable to reproduce the exception on any of my devices, but there seem to be quite a few visible in the Google Play DevConsole.
