有某种onTerminate（）方法，在那里我可以做一些清理（我想清楚了一些共享preferences）时，我的Andr​​oid应用程序将终止？

Is there some sort of onTerminate() method where I can do some cleanup (I want to clear some SharedPreferences) when my Android app is terminating?

我有一个保持几个数字的平均运行的活动，那我存储在共享preference。我希望在应用程序运行（用户可以在不同的活动之间移动），这个平均到最后，所以我不能清除它的onDestroy（）为特定的活动。我需要能够将其清除，一旦应用程序即将退出。

I have an Activity that is keeping a running average of a few numbers, that I'm storing in a SharedPreference. I want this average to last while the app is running (the user can move between different activities) so I can't clear it on onDestroy() for that particular activity. I need to be able to clear it once the app is about to quit.

我怎样才能做到这一点？

How can I do this?

推荐答案

因此​​Android并没有真正有一个应用程序的概念被汉化。 Unfortunently没有什么同义于onTerminate（）。有一些标准，通过它可以决定何时清除您的移动平均值？

So android doesn't really have a concept of an app being "finished". Unfortunently there is nothing synonymous to "onTerminate()". Is there some criteria by which you can decide when to clear your running average?
