I've seen too many bugs on clients devices which I cannot reproduce on my own devices. So far, the only solution was to publish hidden app and let them report all app crashes.
Is there a better way?
Namely, the app is crashing on clients tablet, while it does not on my. How can I catch this crash?
try using ACRA library https://github.com/ACRA/acra but you need to publish a new version in this case.
