GoogleApiClient：Games.API和Auth.GOOGLE_SIGN_IN_API不能一起工作

Question

我有一個使用Google帳戶登錄的工作應用程序。

我建立我的客戶這樣

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

GoogleApiClient googleApiClient = new GoogleApiClient.Builder(this) 
       .addApi(Auth.GOOGLE_SIGN_IN_API, gso) 
       .addConnectionCallbacks(this) 
       .build(); 

現在我決定增加導致以下客戶端的Games.API：

GoogleApiClient googleApiClient = new GoogleApiClient.Builder(this) 
     .addApi(Games.API) 
     .addScope(Games.SCOPE_GAMES) 
     .addApi(Auth.GOOGLE_SIGN_IN_API, gso) 
     .addConnectionCallbacks(this) 
     .build(); 

然而，當我嘗試連接客戶端

googleApiClient.connect(); 

我收到以下例外情況：

java.lang.IllegalStateException: Cannot use SIGN_IN_MODE_REQUIRED with GOOGLE_SIGN_IN_API. Use connect(SIGN_IN_MODE_OPTIONAL) instead. 

所以我讀了異常，並修改了我的聯繫電話，以

googleApiClient.connect(GoogleApiClient.SIGN_IN_MODE_OPTIONAL); 

所以現在我沒有得到任何更多的例外情況，但客戶端永遠不會被連接出於某種原因。任何想法爲什麼客戶端現在不連接？

使用

mGoogleApiClient = new GoogleApiClient.Builder(activity) 
      .addApi(Games.API) 
      .addConnectionCallbacks(callbacks) 
      .build(); 

然後

mGoogleApiClient.connect(); 

如果您在控制檯正確配置你的遊戲 - 它會自動連接並獲取訪問遊戲功能（成就和排行榜f或示例）

class GoogleConnectionCallbacks implements GoogleApiClient.OnConnectionFailedListener, GoogleApiClient.ConnectionCallbacks { 

    @Override 
    public void onConnected(@Nullable Bundle bundle) { 
     MyLogger.d("DBG_GGL_LDB", "connected"); 
     Player p = Games.Players.getCurrentPlayer(mGoogleApiClient); 
     String displayName; 
     if (p == null) { 
      Log.w("DBG_GGL_LDB", "mGamesClient.getCurrentPlayer() is NULL!"); 
      displayName = "???"; 
     } else { 
      displayName = p.getDisplayName(); 
     } 
     MyLogger.d("DBG_GGL_LDB", "Hello, " + displayName); 

     if (mGoogleApiClient.hasConnectedApi(Games.API)) { 

      MyLogger.d("DBG_GGL_LDB", "hasConnectedApi true - can user leaderboard"); 
     } 
    } 

    @Override 
    public void onConnectionSuspended(int i) { 
     MyLogger.d("DBG_GGL_LDB", "connection suspended"); 

    } 

    @Override 
    public void onConnectionFailed(@NonNull ConnectionResult connectionResult) { 
     MyLogger.d("DBG_GGL_LDB", "connection failed " + connectionResult.getErrorMessage()); 

    } 
} 

我已經面臨這個問題很長，這是所有使用.addApi(Auth.GOOGLE_SIGN_IN_API, gso)

Answer 2

，因爲代碼工作完全正常比我的測試設備的任何其他設備上。在我的測試設備上重新安裝Google Play之後，它也可以運行！我不知道是什麼導致了問題，但重新安裝它。

原來我根本不需要SIGN_IN。看看Alexanders的答案，如果你需要的話！
