Do NOT use the wakelocks. You might not release it and then you can drain the battery and annoy the user. And it requires additional permissions.

Instead do this in onCreate():

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

If by autolock you mean stop the phone from turning the screen off due to a period of inactivity then you can do the following:

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK, "DoNotDimScreen");

to stop the screen from 'locking':

wl.acquire();

to allow it to lock again:

wl.release();

Im not sure about your question but, i think it refer to keep a application always on.
