退出片段的父 activity 后，Google Fit 步数 return 为零（注销）
GoogleFit Steps Count return zero after exiting the fragment's parent activity (signout)
我正在使用 GoogleFit Api 计算每日步数。我得到了正确的结果。但是当我退出应用程序时（在这种情况下，应用程序退出 Googlefit 片段的父级 activity）
再次登录后，我再次访问相同的片段，但 Googlefit returns stepsCount 为零并且在 result.await 处超时。
这是我的代码。
