This may not be necessary. You will have onPause() called when the screen is turned off, which is the usual situation while the lock screen is up -- so you would only be unpaused when the screen is turned on with the lock screen, which is not that often. The behavior of going to sleep is slightly different in the emulator than the real device, which may be causing problems. This is something you might want to spend more time on when able to run on real hardware.
