in this post here: Android Studio - Error in Activity Call I told you the problem you were facing.
In short...
I developed an app (game) with buttons that call screens. The idea is like this:
Screen 1 - start Screen 2 - choose character Screen 3 - knows object 1 Screen 4 - play with object 1 Screen 5 - knows object 2 Screen 6 - play with object 2 Screen 7 - knows object 3 .... follows the pattern..
I decided by finishing the activities and releasing the various media player.
On my mobile phone it is working well all stages (screens). But when I went to put in other phones, the app again gives problem. It stops working on the same screen that it stopped on my phone. When it stops, it goes back to home screen, I believe that proves that all previous screens were finished. I can’t understand what’s happening. Help! -
It is extremely important you check the Android versions on which you are trying to run your app. There’s no way we know the problem just with your story.

I understand. On my mobile the version is 5.0.2 and the other test is 6.0.1

So for example, in 6.0.1 you have the real-time permission system other than 5.0 below. Make sure there is something related to the permissions.
