Question

我已使用Firebase在我的应用程序中实现了通知，而在Firebase文档中，它建议您在使用通知时需要检查Google Play服务。

我已实施支票：

  public static void checkGooglePlayServices(final Activity activity) {
    GoogleApiAvailability.getInstance().makeGooglePlayServicesAvailable(activity);
  }

如果Google Play服务已过期，用户会收到更新对话框。如果用户跟进并更新了Google Play服务，则返回应用程序（更新完成后），并且用户返回上一个活动，我将在下面发生崩溃：

我不知道为什么我会遇到这次崩溃以及在哪里处理它？</ p>
