Firebase Google Anmelden Implementierung

Question

Ich bin ein wenig verwirrt darüber, was ich authWithOAuthToken für Parameter passiere.

Bedeutet es das Webanwendungstoken, das von der Google Developer Console oder dem Android-Gerät bereitgestellt wird?

Ex Code:

if(googleSignInResult.isSuccess()){ 
     Log.d(TAG,"Google Login Successful"); 
     GoogleSignInAccount account = googleSignInResult.getSignInAccount(); 
     final String idToken = account.getIdToken(); 
     final String name = account.getDisplayName(); 
     final String email = account.getEmail(); 
     root.authWithOAuthToken("google", Constants.GOOGLE_OAUTH_KEY, new Firebase.AuthResultHandler() { 
      @Override 
      public void onAuthenticated(AuthData authData) { 
       //Authenticated 


      } 

      @Override 
      public void onAuthenticationError(FirebaseError firebaseError) { 
       Log.d(TAG,firebaseError.getDetails()); 
      } 
     }); 

Constants.GOOGLE_OAUTH_KEY ist der Schlüssel Client-ID von Google-Entwickler-Konsole zur Verfügung gestellt. Immer, wenn ich versuche, mich mit Google anzumelden, gebe ich onAuthenticationError ein und {"providerErrorInfo": {}} wird zum Loggen ausgedruckt. Gibt es etwas, was ich tun muss, um das richtige OAuth Token zu erhalten?

Answer 1

Der OAuth-Schlüssel, den Sie übergeben müssen, ist nicht die Schlüssel-Client-ID, die von GoogleDeveloperConsole bereitgestellt wird.

Um diesen Schlüssel abzurufen, müssen Sie die Laufzeit dafür fragen.

Werfen Sie einen Blick auf here, um ein Beispiel zu sehen.

Answer 2

Laden Sie den Quellcode von hier herunter (Firebase Google Login Android). In diesem Tutorial habe ich auch die Screenshots geteilt.

Fügen Sie diese Abhängigkeiten:

compile 'com.google.firebase:firebase-core:9.0.0' 
compile 'com.google.firebase:firebase-messaging:9.0.0' 
compile 'com.google.firebase:firebase-auth:9.0.0' 
compile 'com.github.bumptech.glide:glide:3.5.2' 
compile 'com.google.android.gms:play-services-auth:9.0.0'
