登录在与谷歌游戏服务

Question

我根据这篇博客与谷歌的流程来实现新的登录：api-updates-for-sign-in-with-google

但是在登录我得到以下异常：

IllegalStateException: Auth.GOOGLE_SIGN_IN_API cannot be used with Games.API

我建设我GoogleApiClient这样的：

final GoogleSignInOptions googleSignInOptions = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN) 
     .build(); 
mGoogleApiClient = new GoogleApiClient.Builder(this) 
     .enableAutoManage(this, this) 
     .addApi(Auth.GOOGLE_SIGN_IN_API, googleSignInOptions) 
     .addApi(Games.API) 
     .build(); 

当我删除.addApi(Auth.GOOGLE_SIGN_IN_API, googleSignInOptions)我得到以下exceptoin：

java.lang.NullPointerException: Appropriate Api was not requested.

我缺少的东西或新的流动不支持Games.API？

Answer 1

在这个community中有一个类似的错误。

错误消息似乎很清楚，目前这是不可能的：游戏有它自己的登录流程。是否有一个特定的原因，你使用两个？

这是Implementing Sign-in In Your Games的参考。

Answer 2

IMO，你可以参考下面的示例代码：

... 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_games); 

    mGoogleApiClient = new GoogleApiClient.Builder(this) 
      .enableAutoManage(this, this) 
      .addApi(Games.API).addScope(Games.SCOPE_GAMES) 
      .build(); 
} 

@Override 
protected void onStart() { 
    super.onStart(); 
    mGoogleApiClient.connect(); 
} 

@Override 
protected void onStop() { 
    super.onStop(); 
    mGoogleApiClient.disconnect(); 
} 


@Override 
public void onConnected(Bundle bundle) { 
    Log.i("Result", "onConnected"); 
} 

@Override 
public void onConnectionSuspended(int i) { 
    // Attempt to reconnect 
    mGoogleApiClient.connect(); 
} 

@Override 
public void onConnectionFailed(ConnectionResult connectionResult) { 
    Log.e("Result", "onConnectionFailed"); 

    // If the connection failed, in most of time this means user hasn't logined yet 
    // In this case invoke the `startResolutionForResult` will launch the login dialog and account picker 
    try { 
     if (connectionResult.hasResolution()) { 
      connectionResult.startResolutionForResult(m_activity, RC_SIGN_IN); 
     } 
    } catch (IntentSender.SendIntentException e) { 
     e.printStackTrace(); 
    } 
} 
...
