如何从非启动器 android 活动中查找 HOME 键按下暂停原因

Question

When HOME button is pressed activity goes pause state but if the activity is NOT a launcher or MAIN activity then I want to find actual reason why the top activity goes pause state.

Would someone suggest how I can get pause reason from a non-launcher/ non-home activity which is on top before goes to pause due to HOME button press action?

Answer 1

That's ecpected behavior. The HOME button brings up the launcher app. That means the launcher app's activity is now the foreground activity. There is only one foreground activity in Android at a time. That means whatever was previously the foreground activity will be paused, then stopped (unless for some reason part of it remains on screen, which would be weird but possible with a 3rd party launcher I suppose).

Why don't you think it should be paused? I think you don't understand how activity lifecycles work.
