Is it possible to override the functionality of the android power button ? I want to 'disable' the power button. My plan is to override the functionality of this button to do nothing ( {}; ) Well my main idea is to disable the turning the screen off.
I want when someone press the power button nothing to happen.
How can I do this ?

Fortunately, this is not possible, except perhaps via custom firmware.

It works on Cyanogenmod: http://review.cyanogenmod.com/#/c/18924/4/core/res/AndroidManifest.xml you would need the android.permission.PREVENT_POWER_KEY permission.
Btw one good scenario is to use the power button as a camera shutter button (if the device does not have a dedicated one).
Afaik system apps can intercept the power button normally.

Try implementing onKeyDown, and if the given key pressed keycode is KEYCODE_POWER and the action is ACTION_DOWN and right after it ACTION_UP return true (means you handled this key press)
