Answer 1

Steps to reproduce:
Enable developer option "Don't keep activities"
Run application
Start other package activity
Press back -> crash
I have fixed it this way:
#Override
protected void onSaveInstanceState(Bundle outState) {
//super.onSaveInstanceState(outState);
}
If you don't need to save an activity state, it is quite a good solution.
