Answer 1

I had same issue and reached to user who gets crash by phone. User says that he cloned my app with a third party application and he's trying to use both apps in same device and gets crash.

With a quick search, i found some applications in Google Play which clones apps.

I'm not sure if there's a valid way for handling this crash such as trying to get support from Google or is it right to take action for this issue. For now, i'll ignore the crashes cause only 1 user gets these crashes.

Good luck.
