Android Will the CountDownTimer remain counting when device goes to sleep?

I am using a CountDownT开发者_如何转开发imer to log a user out of my app after a specified time. I am wondering if the Timer keeps going even if my app is sent to the background or if the phone locks because the user put their phone down? If anyone thinks I should use a different timer method please let me know.

Thanks

The CountDownTimer wll not work when the phone goes to sleep:

When I stopped using wakelock, the CountDownTimer never finished. Works with wakelock though.
