Question

我有一个使用Google帐户登录的工作申请。

我正在构建我的客户端

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();

现在我决定添加Games.API，导致以下客户端：

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

但是当我尝试连接客户端时

googleApiClient.connect();

我得到以下异常：

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

所以我读了异常并修改了我的连接调用

googleApiClient.connect(GoogleApiClient.SIGN_IN_MODE_OPTIONAL);

所以现在我不再获得任何例外，但客户端由于某种原因从未连接过。客户现在没有连接的任何想法？

使用

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

然后

mGoogleApiClient.connect();

如果您在游戏机中正确配置游戏 - 它将连接并访问游戏功能（例如成就和排行榜）

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());

    }
}

我长期以来一直面对这个问题，这完全是因为使用.addApi(Auth.GOOGLE_SIGN_IN_API, gso)

Answer 2

代码在我的测试设备之外的任何其他设备上运行得非常好。在我的测试设备上重新安装Google Play后，它也有效！我不知道是什么导致了这个问题，但重新安装修复了它。

原来我根本不需要SIGN_IN。如果你需要，请看Alexanders的答案！

GoogleApiClient：Games.API和Auth.GOOGLE_SIGN_IN_API无法合作
