Random black screen when launching Android application on device

Question

When I launch my application from the Android studio on the device or when I download and install it from a direct APK file, sometimes there is a black screen , and after a few seconds a request appears with the application crashing a message.

There is no information about this in logcat, except:

Wrote the stack trace in '/data/anr/traces.txt'

So, I opened this file, but I do not understand what I have to look inside it.

Perhaps abstract lines:

Maybe I'm wrong, but can these crashes appear in Google Analytics?

Any help with these random glitches?

Thanks;)

Answer 1

Same problem. I just updated Google Play Services and I use:

 compile 'com.google.android.gms:play-services-base:6.5.87' compile 'com.google.android.gms:play-services-plus:6.5.87' compile 'com.google.android.gms:play-services-ads:6.5.87' 

I decompiled the code, and it looks like GoogleAnalytics.getInstance() synchronizing with an instance of GoogleAnalytics.class , and there are two more asynchronous streams that use another getter static GoogleAnalytics eY() , which is also synchronized. I cannot understand what is happening (the code is messy), but I think this is a problem in the library.

EDIT: The issue is also reported here: https://code.google.com/p/android/issues/detail?id=82157 . Removing the global configuration from the manifest resolved the issue for me.

Answer 2

I fixed this problem, but disabled the disconnect of Google Analytics, which I sent.

In our project, we use the boolean value:

 boolean isDeveloperMode = true; // Don't send unless it a public build 

Bug fixed :)
