First, you need to acquire() the WakeLock to have it take effect.

Second, if your application has a UI, and you only want to keep the screen on while your UI is in the foreground, remove all of your WakeLock logic and just call setKeepScreenOn(true) on any widget in your UI.

Read The Friendly Manual: http://developer.android.com/reference/android/os/PowerManager.WakeLock.html

You need to call:

wl.acquire()

And then

wl.release()
