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.

android: The google maps 8.4.0 version is crashing for some devices

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.
The stack trace is not giving any details:

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.

ActionBarSherlock BadParcelableException: ClassNotFoundException when unmarshalling

I'm using a combination of ActionBarSherlock and ViewPagerIndicator in my app. I have an activity which contains a ViewPager that uses a FragmentStatePagerAdapter to scroll between the tabs. One of the fragments contains an IcsSpinner. When the activity state is restored and I scroll to the tab with the IcsSpinner i get the following exception:
