KeyEvents stackoverflow This link lets you know how to handle onKeyUp/Down event.

For Back key detection use KEYCODE_BACK

For Volume Keys use KEYCODE_VOLUME_DOWN and KEYCODE_VOLUME_UP

list of Key events

Detecting menu button

OnStop() lifecycle method of a activity is called when power button is pressed.
