timer - Pause CountDownTimer in Android when activity is not in front

Question

I have an activity that uses a CountDownTimer that counts down from 10. How do I pause that timer when the activity is no longer in focus, like if the user get a call or something, then resume the timer when the user goes back to the activity? Is this even possible?

Answer 1

I would add something to the onTick handler to save the progress of the timer in your class (number of milliseconds left).

In the onPause() method for the activity call cancel() on the timer.

In the onResume() method for the activity create a new timer with the saved number of milliseconds left.
