2 Activities get notified on GPS Status Changed

Question

I have A Activity and B Activity, both implement LocationListener. So both have

@Override
public void onProviderDisabled(String provider) {
    // Open AlertDialog
}

I start B Activity from A Activity. When i turn off GPS on B, it opens AlertDialog as shown on code, then i turn on GPS and dismiss AlertDialog. Now when i return back to A Activity it shows AlertDialog too because it get notified when GPS is turned off few seconds ago.

I think even i opened B from A, A is not destroyed completely and is saved on backstack. So how do i solve this problem without removing A from Activity Backstack ? App should only open AlertDialog on whichever Activity is on the screen.

stop listening gps in Activity A's onPause or onStop method. and start listening in onResume. — SRB Bans, Dec 02 '15 at 14:38
@sourabhbans yes i was just trying that. Because i was stopping to listen on `onDestroy` — Jemshit, Dec 02 '15 at 14:39
Ok that did trick, again i need to start to listen when i return back from `B`, and i did that too :) @sourabhbans you can write it on answer — Jemshit, Dec 02 '15 at 14:44

You should stop listening gps in Activity A's onPause or onStop method. and start listening in onResume. like : in A

onStop(..){
// stop gps listening here
}

and again when return from B..

onResume(..){
// start gps listening here
}
