Google Вход Failed - Firebase

Question

Я после этого tutorial и в этой части кода:

@Override 
    public void onActivityResult(int requestCode, int resultCode, Intent data) { 
     super.onActivityResult(requestCode, resultCode, data); 
     // Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...); 
     if (requestCode == RC_SIGN_IN) { 
      GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data); 
      if (result.isSuccess()) { 
       // Google Sign In was successful, authenticate with Firebase 
       GoogleSignInAccount account = result.getSignInAccount(); 
       firebaseAuthWithGoogle(account); 
      } else { 
       // Google Sign In failed 
       Log.e(TAG, "Google Sign In failed."); 
       Toast.makeText(SignInActivity.this,"Google Sign In Failed.",Toast.LENGTH_SHORT).show(); 
      } 
     } 
    } 

Я получаю знак Google в не удалось. Я не знаю, что не так, как исправить?

Я действительно получил работу, когда попытался запустить app-released.apk вместо работы непосредственно на своем телефоне.

Я внедрил Google Signin в свой проект. Вот код.

Answer 2

Сначала проверьте, что ваш проект правильно настроен в консоли API. Следуйте за this ссылкой в ​​качестве ссылки (некоторые говорят, что вы должны использовать .json, сгенерированный в этой ссылке, потому что одно из консоли не работает).

Другая вещь, был ли отображен экран выбора учетной записи? Можете ли вы распечатать статус и получить код статуса?

Answer 3

Возможно, вы перепутали/не настроили свой сертификат отладки (может случиться, если вы переключитесь на другую машину разработки с различным набором ключей). Убедитесь, что вы добавили SHA1 сертификата отпечатка в разделе Firebase Настройки консоли вашего проекта, как описано здесь: https://firebase.google.com/docs/auth/android/google-signin#before_you_begin
