Re: [Firebase] FirebaseAuth in application class and Firebase crash reporting exception

[Samuel Stern]

This error is happening because FIrebase Crash reporting adds a second process to your app (so it can catch crashes in the main process).  This means your Application onCreate method is being called twice.  However FirebaseApp is initialized by the FirebaseInitProvider ContentProvider, which has a different lifecycle.

I would strongly suggest not doing authentication in your Application class, but if you really need to you can avoid this error by checking FirebaseApp has been initialized using FirebaseApp.getApps().size() before making the call to FirebaseAuth.getInstance(), which implicitly calls FirebaseApp.getInstance().

If I have a class that extends Application. And I try to sign in anonymously

public class MainApplication extends Application {

        firebaseAuth.signInAnonymously().addOnCompleteListener(task -> {

}

And at the same time I am trying to use firebase crash reporting. 

compile 'com.google.firebase:firebase-crash:9.2.1'

I encounter this crash.

If I dont use crash reporting there is no exception.

If I move the sign in code into an activity class it seems to work ok.
