Keep Screen On(Not sleep)
Basically, when running Android application.
Device sleeps some times after no operation(this is user setting).
But, we don’t want the device sleep for some reasons.
Keep on
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
getWindow() is Activity method
Clear this settings
If you restore settings please use it
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
just flag off.
