I set up Firebase crashlytics following's Google's instructions (https://firebase.google.com/docs/crashlytics/get-started?platform=android&authuser=1#add-sdk), then I purposely crashed the app in order to see something in the firebase console, as per https://firebase.google.com/docs/crashlytics/test-implementation?authuser=1&platform=android.; this page also suggests turning on the crashlytics debug logging, which I did. The logging ends with:

D/FirebaseCrashlytics(23841): Crashlytics is handling uncaught exception "java.lang.RuntimeException: Unable to start activity ComponentInfo{com. ... .TabActivity}: java.lang.NumberFormatException: Invalid int: "abc"" from thread main

D/FirebaseCrashlytics(23841): Crashlytics completed exception processing. Invoking default exception handler.

According to this SO post, I should be expecting, after "Crashlytics report successfully enqueued to DataTransport", some lines like

TransportRuntime.CctTransportBackend: Making request to with subsequent 
TransportRuntime.CctTransportBackend: Status Code: 200

But it wasn't there.

People also say it takes 24-48 hours for crash data to show up in the console, rather than "up to 5 minutes" like what Google says. But it is over 48 hours now.

  • At this point I'd suggest you to open a support ticket, they can search the ID from the line "enqueue to DataTransport" and check if the report was received. Try sending all the info like the logs and Firebase project info. https://firebase.google.com/support/troubleshooter/crashlytics/missing – Gerardo Mar 04 '21 at 07:12

Even though this was for Android, an important clue was found in the iOS instructions on testing with a forced crash, namely, that the app should run long enough the next time, or in a subsequent run, that it has time to send the crash logs to Firebase. If you fake an automatic crash early in the app lifecycle for testing purposes, it may not have time to send the data about earlier crashes when it starts again later, before it crashes again.
