This approach sets the time at which an idle screen turns off. It does not actively turn off the screen. – user462990 Aug 10 '12 at 11:03

This will turn the screen off for the specified amount of time:

PowerManager manager = (PowerManager) getSystemService(Context.POWER_SERVICE);
manager.goToSleep(int amountOfTime);

It should be pointed out that this requires signature permission DEVICE_POWER, which most applications are unlikely to hold: http://stackoverflow.com/questions/5710971/android-what-permissions-required-to-call-powermanager-gotosleepn-put-device-i – Rupert Rawnsley Jun 18 '12 at 13:40
