My application has been published for a while. I have never received any crash reports through Google play developer page. Then I integrated Flurry to see how the audience is behaving. On Flurry dashboard I saw that my application occasionally crashes. The crashes are irregular and produce very different stack traces. I cannot understand why the crashes appear and I cannot reproduce them on my devices and emulators - application just works perfectly. My problem is that it is difficult to fix something that really works for you :)
Flurry dashboard shows that the crash ratio is 1-2% of the sessions - not that big. So I was thinking just to accept that. But the crashes still bother me in the back of my head. I want your advice - should I accept this small crash ratio or really investigate the crashes? What crash ratios do you have for your applications ?
