As an alternative to WakeLock, I'd suggest using the FLAG_KEEP_SCREEN_ON flag.

getWindow().setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON, WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

This is easier to use than WakeLock, as you don't need to worry about releasing it when the activity is paused/destroyed.

Window flag: as long as this window is visible to the user, keep the device's screen turned on and bright.

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.SCREEN_BRIGHT_WAKE_LOCK , "My Tag");
wl.acquire();
 // ..screen will stay on during this section..
wl.release();

Nb. the keyboard backlight will be allowed to go off.
