Hi I have application with more than 20 activities.I want to close my app when Home button is pressed.

推荐答案

还有就是关闭我的应用在Android的概念。 Android将摆脱你的活动，其次是你的过程，一段时间没有用户后。

There is no notion of "close my app" in Android. Android will get rid of your activities, followed by your process, after some period of inactivity by the user.
