我已经登录了google plus，但是当我登录成功时，在新的活动中，我注销了，再次登录后，它不是成功登录。日志：ClearcutLoggerApiImpl：断开托管 GoogleApiClient

它是代码：

GoogleSingleton:
public class GoogleSingleton {
    private ILogInGoogleListener mListener = null;

    public void setLogInGooglePlusListener(final ILogInGoogleListener listener) {
        this.mListener = listener;
    }

    public interface ILogInGoogleListener {
        void logInGooglePlusSuccess(String name,
                                    String email,
                                    String pid);
    }
