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 som

Answer 1

For Kotlin user, checkout this

For eg:

// Init timer
lateinit var timerExt: CountDownTimerExt

timerExt = object : CountDownTimerExt(TIMER_DURATION, TIMER_INTERVAL) {
    override fun onTimerTick(millisUntilFinished: Long) {
        Log.d("MainActivity", "onTimerTick $millisUntilFinished")
    }

    override fun onTimerFinish() {
        Log.d("MainActivity", "onTimerFinish")
    }

}

// Start/Resume timer
timerExt.start()

// Pause timer
timerExt.pause()

// Restart timer
timerExt.restart()
