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()?

Answer 1

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.
