Google-Anmeldung requestIdToken gibt null zurück

Question

Ich verzweigte this google Beispielprojekt und lief das android Signin.

Ich habe die Optionen in der Google Developers-Konsole eingerichtet und eine Client-ID erhalten, aber beim Ausführen des Projekts kommt das ID-Token auf Null.

Der vollständige Code ist here
Dieser Code fordert das ID-Token an.

GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN) 
      .requestIdToken(getString(R.string.server_client_id)) 
      .requestEmail() 
      .build(); 

Ich vermisse etwas im Setup, irgendwelche Vorschläge.

Hier ist die Log

Answer 1

Wie ich kommentiert und als Google in der Dokumentation, sollten Sie "Web-Anwendung" Typ Client-ID, statt "Android" Typ Client-ID verwenden.

wie der folgende Screenshot:

Answer 2

Use "default_web_client_id" in GoogleSignInOptions

GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN) 
       .requestIdToken(getString(R.string.default_web_client_id)) 
       .requestEmail() 
       .build(); 

Es funktioniert perfekt.
