Thanks in advance.

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.
