From android 4.0+, it supports to take screenshot by pressing volumn down+power keys. I'm going to use the screenshot image immediately when after taking screenshot by the hotkey.
Is there any Android SDK API to be used as a callback of the event? then I can register such listener to the event of taking screenshot.
Will taking screenshot by vol down+power send some public broadcast? then I can receive this public broadcast.
Is there any way to capture hotkey events? When pressing volumn down+power at the same time, can I get a notification?
Appreciate if any one can help on this. thanks.
