saving activity state on close of the app by back key press
<p>I am creating an App. It has 4 count-down timers. 
   My problem is,
         In the middle of the count-down timer running user may press the back key and close the App. <strong>I want to let the countdown-timer run it's count so that the user can see the updated version of it when he opens the App on next time.</strong> 
        I thought to manage the state using onSaveInstanceState Callback but I read in the document that it been not called on the event of back key press of the activity. And I tried to check...yes it is not. Is any chance I can solve this using services?</p>

<p>Can someone shed some light on this please. </p>

<p>Note: I am using Handler.postDelayed for running count-down timers. </p>

<p>Thanks</p>
