Ignoring navigate() call: FragmentManager has already saved its state

You must always call super.onActivityResult() in your Activity's onActivityResult. That is what:

1. Unlocks Fragments so they can do fragment transactions (i.e., avoid the state is already saved errors)

2. Dispatches onActivityResult callbacks to Fragments that called startActivityForResult.

Finally, I fix the issue by simple calling super.onPostResume() right before navigating to restore state.
