If we use our native library using System.loadLibrary() then SupportMapFragment just kills activity after few seconds when it's launched. And it does that without any stacktrace. This is the best log I could collect:

I have spent few days trying to understand what was causing it and it seems if we remove System.loadLibrary() call i.e. not use our native lib then SupportMapFragment works fine. Is there any way I can resolve it without removing our native lib?
EDIT: I created a sample app to reproduce this issue and after the above mentioned log I also got something which seems useful:
