I am creating an Android application and I\'m currently trying to implement user authentication using Firebase. As far as I can tell, my app is connected to my Firebase serv
I know there's already an accepted answer. However, I ran into the same error message saying: java.lang.IllegalStateException: Default FirebaseApp is not initialized in this process (name). Make sure to call FirebaseApp.initializeApp(Context).
I tried several solutions found on SO, and double checking everything, until I finally found that the package name defined in the Firebase Console didn't match the package name defined in my manifest file.
Try go to your Firebase Console -> Project settings -> check if package names matches.
Hope it may help some :)
