Why javascript continues after I close my android app?

Question

I made an android app that shows an internal html with javascript in a webview. The javascript has an infinite loop to update the view once each minute.

The problem is that after I close my app with the back button, the javascript continues its infinite loop... Why is this happening and how can I prevent this?

Thanks! L.

"close the app with the back button" ... the back button doesn't close apps on any Android device I've ever used. — Pointy, Apr 07 '14 at 21:23
maybe disable the javascript of the webview in the onPause method and re-enable in the onResume. — donfuxx, Apr 07 '14 at 21:25
@LuisA.Florit yes I guess that's true, but that's still my point - the app has to decide to stop and then do so. — Pointy, Apr 07 '14 at 22:52

Why is this happening

Because you did not stop the loop. It will keep going until Android terminates the process.

how can I prevent this?

Stop the loop. You really should be stopping it in onPause() or onStop(), picking it up again (if needed) in onResume() or onStart().
