You could have a look at [Unfortunately MyApp has stopped. How can I solve this?](https://stackoverflow.com/questions/23353173/unfortunately-myapp-has-stopped-how-can-i-solve-this) to get properly started on the problem solving and maybe then update the question with any relevant details. — Markus Kauppinen, Jun 19 '19 at 12:31
