Android system creates a snapshot of your app activity and display it when you access reccent items on defaut button of your android device.
Is there a way you can tell android what to display on this snapshot ! the reason for that is I want to hide completely what ever I was doing before closing the app !!
I can control this snapshot when pressing backkey or when user exits the app but when pressing home button it is not possible.
I think presently there is no solution to trap 'home' key.
I use it in many of game apps which do not respond properly to back keys, to close them, from recent menu.
So I think Android OS does not allow to trap 'home' key.
