推荐答案

我实现通过重写类似 Activity.onUserLeaveHint（）。此方法被调用一次，home键是pressed但我觉得在那里有一些注意事项我不记得现在。即它得到了号召情况下，我不希望我的应用程序完成，并不得不把标志prevent不必要的退出。

I implemented something similar by overriding Activity.onUserLeaveHint(). This method gets called once home key is pressed but I think there where some caveats I can't remember right now. Namely it got called on situations I didn't want my application to finish and had to put flags to prevent unwanted exits.
