Prevent screen from going to sleep

Question

How to prevent mobile device (Android or iOS) to put screen to sleep?
I'm using Flash CS6 + AIR, in publish settings under Permissions I do have these two marked: DISABLE_KEYGUARD and WAKE_LOCK. But I don't see it working, i'm testing on Samsung Galaxy S3 (latest Android OS).
Although it says it only needs to be in XML file those two lines, don't I have to put anything in ActionScript 3.0 code inside my Flash document ?
When I pack APK file is XML also packed there ?
Thanks

These functions will give you an idea of what you have to do on the AS3 side:
import flash.desktop.NativeApplication;
import flash.desktop.SystemIdleMode;
stage.addEventListener(Event.ACTIVATE, fl_Activate);
stage.addEventListener(Event.DEACTIVATE, fl_Deactivate);
private function fl_Activate(event:Event=null):void {
     NativeApplication.nativeApplication.systemIdleMode = SystemIdleMode.KEEP_AWAKE;
private function fl_Deactivate(event:Event):void {
     NativeApplication.nativeApplication.systemIdleMode = SystemIdleMode.NORMAL;
The XML, where you have set the wake lock permissions for Android, does end up in the APK.
