推荐答案

简短的答案是……没有！

The short answer is ... there aren't!

关闭应用程序"的概念非常分散:应用程序是一组活动，服务等，并且很多事情可以使该应用程序保持活动状态.

The concept of "application close" is very diffuse: An application is a set of activities, services, etc... and a lot of things may keep the application alive.

您甚至无法猜测何时(或是否)将调用活动onStop()和onDestroy().

You can't even guess when (or if) an activity onStop() and onDestroy() will be called.

即使调用activity.finish()也不意味着这些方法中的任何一种都会被立即调用.看看 http://developer.android.com/training/basics /activity-lifecycle/stopping.html .

Even calling activity.finish() doesn't mean any of those methods would be called instantly. Take a look at http://developer.android.com/training/basics/activity-lifecycle/stopping.html .

但是，肯定有一个更好的地方来做您必须做的事情.什么事?

But there's sure a better place to do those things you have to do. What is it?
