onUserLeaveHint 홈키 눌럿을때 이벤트

https://developer.android.com/reference/android/app/Activity

Activity  |  Android Developers

 

Called as part of the activity lifecycle when an activity is about to go into the background as the result of user choice. For example, when the user presses the Home key, onUserLeaveHint() will be called, but when an incoming phone call causes the in-all Activity to be automatically brought to the foreground, onUserLeaveHint() will not be called on the activity being interrupted. In cases when it is invoked, this method is called right before the activity's onPause() callback.

 

 

액티비티가 유저에 의해 백그라운드로 갈 때 불리는 이벤트. 보통 홈키버튼을 누르면  발생한다.

 

액티비티에서 다른 액티비티를 호출했는데 퍼미션을 물어볼때도 불리는데.. 이유는 모르겠다.
