Can't get Crashlytics on Android to work, getting runtime error message

Question

I'm having trouble getting Firebase Crashlytics to work in my Android Studio project. I keep getting these runtime errors:

E/FirebaseCrashlytics: Settings request failed.
    java.io.FileNotFoundException: https://firebase-settings.crashlytics.com/spi/v2/platforms/android/gmp/xxxxxxx:android:xxxxxxxxb/settings?instance=xxxxxxx8&build_version=2&display_version=2.0&source=1

I've tried completely removing Firebase from the project and removing the project from Firebase, in other words starting from scratch, but this isn't working either. What could be going on here?

Answer 1

I solved this by migrating my project to a new Firestore project and replacing google-services.json in my Android Studio app folder. I then invalidated cache/restart and I was able to enable Crashlytics in Firestore by forcing an app crash per documentation instruction.
