I have Craslytics integrated in an app for long time. I'm using Proguard to obfuscate the code. Everything was working fine, I was getting my crash reports deobfuscated without problems.
Last week, I enabled the integration of Craslytics in Firebase and since then the crash reports are not being deobfuscated, neither in Crashlytics nor Firebase (I do get the crash reports in both places).
I'm using crashlytics:2.8.0 in production (I'll update to crashlytics:2.9.1 in next week's release). And I have all Proguard rules indicated in the docs (Configure ProGuard and DexGuard).
I've noticed that the release notes from crashlytics:2.9.0 say:
App teams who use both Fabric and Firebase can now link their apps and use Crashlytics within the Firebase console (requires Firebase Core, version 11.4.2+ recommended).
Does that means that I shouldn't have linked Crashlytics with Firebase before updating to crashlytics:2.9.1? Can that be the source of the problem?
Thanks for your help.
After updating Crashlytics from 2.8.0 to 2.9.1 I started to get deobfuscated crash reports again in both Crashlytics and Firebase.
