WakeLock not working

Question

I have a wake lock set up so that I can still hear the sound when the screen times out or I press the screen lock button. From what I can understand through reading online i

I would be surprised if Di Vero Labs's answer resolved this since Android documentation says those additional flags do nothing with a partial wakelock.

A wakelock is as simple as you are using it, and it should work:

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "sleeplock");
wl.acquire();
//release
wl.release(); 

Note that you will need to check for nulls, and check that it is not already acquired, etc before doing these methods or you may get a null pointer exception.

I think your issue is that you are calling cleanup() which includes the wakelock release so you aren't really holding a wakelock. To make sure this works (though might cause battery drain issues) hold your wakelock upfront, then release when you are done, not before you are done else you'll obviously NOT have a wakelock.

I was having a ton of issues because wakelocks weren't working but believe I nailed down the issue to a custom ROM. So beware! (DONT support custom ROMs, including your own!)
