Firebase Выполнение входа в систему Google

Question

Я немного смущен тем, что я прохожу через authWithOAuthToken для параметра.

Это означает токен веб-приложения, предоставляемый консолью разработчика Google или Android-телефоном?

Ex код:

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 является ключом идентификатор клиента предоставляется консоли разработчика Google. Всякий раз, когда я пытаюсь войти в Google, я ввожу onAuthenticationError и {"providerErrorInfo": {}} печатается в журнал. Есть ли что-то, что мне нужно сделать, чтобы получить правильный токен OAuth?

Answer 1

Ключ OAuth, который вы должны передать, не является ключевым идентификатором клиента, предоставленным GoogleDeveloperConsole.

Чтобы извлечь этот ключ, вы должны задать ему время выполнения.

Посмотрите на пример here.

Answer 2

Загрузить исходный код отсюда (Firebase Google Login Android). В этом уроке я также поделился снимками экрана.

Добавьте эти зависимости:

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'
