		* A proximity wake lock does not prevent the device from falling asleep
		* unlike {@link #FULL_WAKE_LOCK}, {@link #SCREEN_BRIGHT_WAKE_LOCK} and
		* {@link #SCREEN_DIM_WAKE_LOCK}. If there is no user activity and no other
		* wake locks are held, then the device will fall asleep (and lock) as usual.
		* However, the device will not fall asleep while the screen has been turned off
		* by the proximity sensor because it effectively counts as ongoing user activity.
		* </p><p>
		* Since not all devices have proximity sensors, use {@link #isWakeLockLevelSupported}
		* to determine whether this wake lock level is supported.
