Is CountDownTimer cancelled automatically on Activity destroy()?

Question

A question, maybe a little naive...

If I start a 2 minute CountDownTimer in Activity onCreate() and close it with finish() when user clicks a button, does Android cancel it automatically?

Or do I need to explicitly call cancel() in onDestroy()?

Have you ever tried it? Just put a Log.d(...) in onFinish() and see if it is logged. – Orphrey

Just tried. onFinish() seems alive even after an Activity.finish(). – Trompe

You will have to explicitly call cancel in Ondestroy. But better practice is to call cancel in Onpause.
Since if you have paused your activity and you update any Ui elements inside OnFinish of the countdown timer it may throw errors.

Actually onDestroy() is much better and a straight-forward approach. The CountDownTimer won't throw any errors even if its onFinish() is called during onPause(). I tried it. – Insinuating
