使用谷歌登录游戏服务

Question

我正在根据此博客文章api-updates-for-sign-in-with-google

实施google flow的新登录

然而，在登录时，我收到以下异常：

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

我正在构建我的GoogleApiClient：

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)时，我得到以下例外情况：

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

我错过了什么或新流量不支持Games.API？

Answer 1

IMO，您可以参考以下示例代码：

...
@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();
    }
}

错误消息似乎很清楚，目前这是不可能的：游戏有自己的登录流程。您是否有特殊原因使用它们？
