Login with email and google work fine. When i’m trying to login with facebook everything goes well (login in facebook app, accept base permissions) untile I come back to AuthUi page where I get the following error:

[...]W/AuthMethodPicker: Firebase sign in with credential unsuccessful
       com.google.firebase.FirebaseException: An internal error has occurred. [ Unsuccessful debug_token response from Facebook ]

       at com.google.android.gms.internal.zzbly$zza.onTransact(Unknown Source)
       at android.os.Binder.execTransact(Binder.java:453)

Observed Results:

I’ve double checked the facebook app configuration, I’m using the right package (I’ve taken it from the AndroidManifest, as className I’m using “com.firebase.ui.auth.AuthUI” (I’ve tried also with the Activity that start the AuthUI istance), the hash key is good (The facebook login flow goes fine until the end)

Expected Results:

Sign in user with facebook

Relevant Code:

startActivityForResult(
                          AuthUI.getInstance()
                                  .createSignInIntentBuilder()
                                  .setIsSmartLockEnabled(!BuildConfig.DEBUG)
                                  .setProviders(Arrays.asList(new AuthUI.IdpConfig.Builder(AuthUI.EMAIL_PROVIDER).build(),
                                          new AuthUI.IdpConfig.Builder(AuthUI.GOOGLE_PROVIDER).build(),
                                          new AuthUI.IdpConfig.Builder(AuthUI.FACEBOOK_PROVIDER).build()))
                                  .build(),
                          RC_SIGN_IN);
