The latest version of G-Droid has error reporting when the app crashes. I already fixed 2 errors, that users had sent in. Please continue sending them through!
The error reporting happens explicitly via email, so you can review the data before sending it. So nothing is being send, without the user confirming it twice. The feature can be deactivated in the settings if desired.
The reporting mechanism has mostly been copied from the F-Droid client source code ✋😃
