I asked similar question few months/year ago but I am still facing this:
is there a way to:
If I provide someone release APK (local install - not on google play) and he got crash, how can I get the stack so I can understand what is going on
You'll need to create your own reporting sub, maybe using the new firebase services, and have a report sent back to you.
The tricky part will be to detect the crash, I think
