This generally happens when you are using google play-service dependency in your project.
Just downgrade the google play-service dependency to compile 'com.google.android.gms:play-services:8.3.0' and the problem may get solved.

We're facing an issue with the maps is some phones. Here's the open issue in the google repo. None of the comments on the issue is helpful.
We are using 8.4.0 version and we have no clue how to fix or catch this crash.
This is hapening only in some devices example : LGE LG-P970 Android 4.0.4 API 15.
We're using the SupportMapFragment.

Did anybody face this issue? any fix (or work around) is welcome.
Thanks!

I observe this crash in activity which dynamically changes fragments when Android device connected to computer in USB debug mode. Without USB connection application works fine.
