My app won't turn off

Hey, I'm new to AIR. I created a simple test app. It runs fine on my Android, but it won't turn off. When I press the home button, or open other app, my app continues running in the background.

Specs:
Android device: Gallaxy note 3
AIR version: AIR 13.0 for Android
My really simply test script:

Code:

---

package  {
        import flash.display.MovieClip;
        import flash.events.TouchEvent;
        import flash.ui.Multitouch;
        import flash.ui.MultitouchInputMode;
        import flash.events.Event;
        public class test extends MovieClip {
                //create vars
                public var counting:int;
                public function test() {
                        // constructor code
                        Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT;
                        stage.addEventListener(TouchEvent.TOUCH_BEGIN, onTouchBegin);
                }
                public function onTouchBegin(e:TouchEvent):void
                {
                        someText.text = String(counting);
                        counting++;
                }
        }
}

Any help would be appreciated.
