Crashlytics console not showing any crashes anymore

The Problem

All Crashlytic logs randomly stopped showing up on the Firebase Crashlytics console. The crash free rate percentage, however, does show up there. I assume that they are indeed getting some data, because in order to calculate this crash free percentage they need the crash log data (maybe not, idk).

To add to this, older builds where crashes used to be seen, also stopped showing the crash logs in the Firebase Crashlytics console. At this point i am convinced that it might not be a configuration issue on our end, if it was older builds shouldnt be affected.

There are no error logs either, telling us that something is wrong.

What i have tried

Checked to see if we changed anything related to firebase crashlytics (besides updating to the latest version) Updating to the latest firebase Crashlytics version (multiple times) Ive tried comparing the google-services.json file to the one we have in the project, and it is the same. Contacting the firebase team, been at it for a few weeks now and still could not resolve, ive sent the logs, code snippets, everything they asked for. But still no solution. Made sure we no longer have any references to the old crashlytics/fabric plugin/implementation. Project info:

• Kotlin version: 1.4.10
• Gradle plugin version: 4.0.2
• firebase-crashlytics-gradle version: 2.3.0
• Firebase Crashlytics version: 17.2.2

Existing Crashlytics configuration:

(cleaned up to show firebase related only)

Note: We have our google-services.json located in the proper location in our project, as it always been.

@tspecht Alright cool. Well, not cool, but thanks for the info. 😝 I’ll report back when I have more information for you.

Just tested this and it seems to be reporting to the firebase console now

For anyone experiencing this using Dexguard, please update to the latest 8.x version or add this to your obfuscation rules:

-keepresourcexmlelements manifest/application/service/meta-data@value=cct

That should address the issue for future versions of your app.
