I had Firebase Crashlytics installed in my Android app, and the reporting is operational.
However, I found that some issues are very similar:
And it'd be helpful if I could treat them as the same issue when debugging or closing.
Is there any chances I can merge them into one?
It is not possible to merge these crashes. Crashlytics will group the issues based on the frame being blamed. In this case, even though they look similar, the frame is under a different line number.
You could file a feature request for this behavior.
