推荐答案

不要盲目地检查日程表上的更新。而是检查用户何时启动您的应用程序（每次，每10次或每30天，但只有当应用程序使用时）。

Don't blindly check for updates on a schedule. Instead, check when the user starts your application (every time, or every 10th time, or every 30th day, but only when the app gets used).

用户讨厌当他们没有运行的应用程序正在占用资源。

Users hate it when an application they aren't running is taking up resources.

正如Steve Jessop指出的，偶尔再次检查应用程序是否正在运行长时间。

As Steve Jessop points out, it may also be good to occasionally check again if the app stays running for a long time.

安装预定任务仍然是要运行的方式，但将其设置为手动运行，而不是定期运行，那么您的应用程序可以触发它。应用程序可以触发任务，其执行权限高于应用程序本身（首先创建任务需要完全管理权限）。该任务还记住上次运行时间，这对于保持流量非常有用

Installing a "Scheduled Task" is still the way to go, but set it to run manually instead of on a periodic schedule, then your app can trigger it. An app can trigger a task that executes with higher permissions than the app itself (creating the task in the first place requires full admin rights). The task also remembers the last time it ran which is useful for keeping traffic down.
