This one work when you hit the back or home button:
import flash.system.Capabilities;
import flash.desktop.SystemIdleMode;
if (Capabilities.cpuArchitecture == "ARM")
NativeApplication.nativeApplication.addEventListener(Event.ACTIVATE, handleActivate, false, 0, true);
NativeApplication.nativeApplication.addEventListener(Event.DEACTIVATE, handleDeactivate, false, 0, true);
NativeApplication.nativeApplication.addEventListener(KeyboardEvent.KEY_DOWN, handleKeys, false, 0, true);
//==================================================================
public function handleActivate(event:Event):void
NativeApplication.nativeApplication.systemIdleMode = SystemIdleMode.KEEP_AWAKE;
//==================================================================
public function handleDeactivate(event:Event):void
NativeApplication.nativeApplication.exit();
//==================================================================
public function handleKeys(event:KeyboardEvent):void
if (event.keyCode == Keyboard.BACK)
NativeApplication.nativeApplication.exit();
