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

Question

我有一个使用谷歌帐户登录的工作应用程序。

我正在像这样构建我的客户

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，从而生成以下客户端：

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.

所以我阅读了异常并将我的连接调用修改为

googleApiClient.connect(GoogleApiClient.SIGN_IN_MODE_OPTIONAL);

所以现在我没有再收到任何异常，但由于某种原因，客户端从未连接过。知道为什么客户端现在不连接吗？

使用

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

然后

mGoogleApiClient.connect();

如果您在控制台中正确配置了游戏 - 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());
}
}

我已经面临这个问题很长时间了，这都是因为使用.addApi(Auth.GOOGLE_SIGN_IN_API, gso)

该代码在我的测试设备以外的任何其他设备上都能正常工作。在我的测试设备上重新安装谷歌播放后，它也起作用了！我不知道是什么导致了问题，但重新安装修复了它。

事实证明，我根本不需要SIGN_IN。如果你需要，看看亚历山大的答案！
