我正在开发一个游戏为Android使用谷歌玩游戏服务，使用Xamarin。我做用Genymotion Android模拟器我的测试。我遇到了，似乎在任谷歌播放或Xamarin的实现中的错误问题。

I am developing a game for Android using Google Play Game Services, using Xamarin. I am doing my testing using a Genymotion Android Emulator. I have run into an issue that appears to be a bug in either Google Play or Xamarin's implementation.

如果我签了一个谷歌帐户的，则调用 IGoogleApiClient.IsConnected（）继续返回true （即使我有显然刚刚签署了）。如果我再尝试使用该API的对象，我会得到这样的例外：

If I sign out of a Google account, calls to the IGoogleApiClient.IsConnected() continue to return true (even though I have clearly just signed out). If I then attempt to use that API object, I will get exceptions like:

java.lang.SecurityException异常：未签订调用API时

java.lang.SecurityException: Not signed in when calling API

例如，在上面的异常后续code的结果，如果注销后执行：

For example, the follow code results in the above exception if executed after signing out:

public void StartNewMatch()
{
    if (!mGoogleApiClient.IsConnected)
    {
        return;
    }

    Intent intent = GamesClass.TurnBasedMultiplayer.GetSelectOpponentsIntent(mGoogleApiClient, 1, 1, true);
    StartActivityForResult(intent, RC_SELECT_PLAYERS);
}

我签署了在谷歌Play游戏收件箱（匹配选择器）;如下面的图像。

I am signing out in the Google Play Games Inbox (match picker); as shown in the images below.

任何人都碰到过？我失去了一些东西？有任何变通办法？

Anyone run into this before? Am I missing something? Got any work-arounds?

注意：这种情况只发生，如果注销通过谷歌的用户界面如果我手动登录用户了，有像 mGoogleApiClient.Disconnect（），这个问题不会出现; mGoogleApiClient.IsConnected（）现在返回false（如预期）。

@Override
protected void onActivityResult(int requestCode, int responseCode, Intent data) {

    // check for "inconsistent state"
    if ( responseCode == GamesActivityResultCodes.RESULT_RECONNECT_REQUIRED && requestCode == <your_request_code_here> )  {  

       // force a disconnect to sync up state, ensuring that mClient reports "not connected"
       mGoogleApiClient.disconnect();
    }
}
