Default FirebaseApp is not initialized

[AppWerft]

win.addEventListener('open', function() {
    FirebaseCore.configure({
        file:'google-services.json'
    });
});

This simple code above generates:

[ERROR] :  TiBaseActivity: (main) [43,43] Error dispatching lifecycle event: Default FirebaseApp is not initialized in this process de.appwerft.firebauseauth. Make sure to call FirebaseApp.initializeApp(Context) first.
[ERROR] :  TiBaseActivity: java.lang.IllegalStateException: Default FirebaseApp is not initialized in this process de.appwerft.firebauseauth. Make sure to call FirebaseApp.initializeApp(Context) first.

But the error is from TitaniumFirebaseAuthModule. So where in your code do you use TitaniumFirebaseAuthModule.onStart? It looks like this is initialized before win.open()

[AppWerft]

This is a very good thought. I will inspect. I have used the original TitaniumFirebaseAuthModule. My new code comes from a submodule. The question is, when the onStart will fired? I guess:

onAppCreate: if app is started onStart: if the JS layer calls require

The app needs to be configured in the open event of the root window.

I guess the root window will build in app.js as first window. This I did in app.js:

var $ = Ti.UI.createWindow();
$.addEventListener('open',function() {
    FirebaseCore.configure();
    FirebaseAuth.createUserWithEmail({
        email:"rainer@com",
        password:"********",
        callback : function(e) {
            FirebaseAuth.signInWithEmail({
                email:"rainer@com",
                password:"********",
                callback : function(e) {
                    console.log(e);
                }
            });
        }
    });
});

I found in manual: FirebaseApp.initializeApp() return an instance of FirebaseApp.

In next module firebase.auth. in onStart() event in line 76(?) this will call mAuth = FirebaseAuth.getInstance();. If I call a Kroll.method like createUserWithEmail() mAuth is null.

I found: FirebaseCore.configure(); must run before window is opened. So the first (splash) activity will taken.
