android - "This app is not authorized to use Firebase Authentication" in Emulator

Question

I'm getting this error when I try to run my app on emulator.

What I've done:

1. I'm using Firebase-UI and running Android O
2. I have the Play Store updated.
3. I've added all the SHA-1 code to Firebase console and the package name matches.

In fact when I run the app on a real device it runs perfectly and I can login.

This app is not authorized to use Firebase Authentication. Please verify that the correct package name and SHA-1 are configured in the Firebase Console.
 com.google.firebase.auth.FirebaseAuthException: This app is not authorized to use Firebase Authentication. Please verifythat the correct package name and SHA-1 are configured in the Firebase Console. [ App validation failed. Is app running on a physical device? ]
