FLAG_KEEP_SCREEN_ON does not work during keygaurd lock

Question

Hi I am an Android newbie, I want to create an app which stays displayed even if the power button is pressed, I used,

getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);

but I had to press power button again to display the app, someone suggested me to use,

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

but it doesn't seem to work. Is there any work around ?

You can't prevent hardware keys overriding. Power button works on hardware level. Ur app will be unable to turn screen on after it was turned off by hardware.
