Crashlytics not appear crash in dashboard

Question

I added Firebase Crashlytics in my project and I force created a crash with the below code. The crash was created and logged in logcat but didn't appear in Crashlytics dashboard!

I enabled debug logging to my project and I saw the below message when forcing a crash, but I don't know what this is / what the problem is?

I can see my errors in Fabric console but they don't show in Firebase. In Firebase, Analytics reports like users in last 30 minutes work with my application. I've been trying for around 3 days but still can't see the error in my dashboard!

My code:

  Button crashBtn=findViewById(R.id.crashBtn);
    crashBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Crashlytics.getInstance().crash();
        }
    });

My error after enable debug logging with adb:

Answer 1

This happened to me because I had this in the manifest:

        <meta-data
            android:name="firebase_crashlytics_collection_enabled"
            android:value="false" />

Answer 2

Assumption: this happens only to those who migrate from Fabric.

Solution

For those who just do not see any crashes in Crashlytics tab in Firebase Console try manually enabling Crashlytics in your application before initializing FirebaseApp context.

FirebaseApp.initializeApp(this)
FirebaseCrashlytics.getInstance().setCrashlyticsCollectionEnabled(true)
// Optional. Uncomment if you are using analytics. 
// FirebaseAnalytics.getInstance(this).setAnalyticsCollectionEnabled(true)

After rebuilding and installing the application from the Android Studio to the physical device, and generating one more crash, I successfully got a crash report to appear in Firebase Console. Previous reports did not appear (in some part that is to be expected since there were no reports made).

What has triggered me to do this?

I was migrating from Fabric to Firebase, as many do now due to Fabric being deprecated and turned off on 15 November 2020. I enabled logs using adb shell setprop log.tag.FirebaseCrashlytics DEBUG. This is part of testing your implementation. Due to having issues with crash reporting, I enabled that feature to take a look if there is anything useful in these logs.

What I have noticed is that FirebaseCrashlytics loads cached settings if there are any. Reading through them I found an interesting key-value pair that could probably be the issue:

"firebase_crashlytics_enabled":false

This setting was weird. There is one more related to Firebase Analytics: "collect_analytics":false.

Both of them are false for some reason though I never did turn them off explicitly. Never even played with these settings. Only migrated from Fabric to Firebase.

09-25 11:08:50.045 30646 30646 D FirebaseCrashlytics: Loaded cached settings: {"settings_version":3,"cache_duration":86400,
"features":{"collect_logged_exceptions":true,"collect_reports":true,"collect_analytics":false,"prompt_enabled":false,"push_enabled":false,"firebase_crashlytics_enabled":false},
"app":{"status":"activated","update_required":false,"report_upload_variant":2,"native_report_upload_variant":2},
"fabric":{"org_id":"FabricApiKeyWasHere","bundle_id":"your.app.package.name"},
"expires_at":1601028354301}

Enabling Crashlytics, as described at the beginning of this post, I was able to turn crash reporting on and get reports to appear in Firebase Console. Note, that cached settings still have "firebase_crashlytics_enabled":false. Even after multiple reinstalls/reruns of the application.
