Getting back into Flash

I have a couple of questions for folks. I am having some issues and need help sorting them out. First, has anybody done any flash air development for Android. If so, have you found a way to ad support a free application? Question 2 is potentially a little more in-depth. I have been out of flash since Flash MX and have not really used AS3 before but it is requirement to do Android conversions. I am trying to build a simple flash card type of application. I am loading an external XML file with content in it. I have pasted the code below:


import flash.events.MouseEvent;
var my_korean:XMLList;
var my_english:XMLList;
var my_actiontype:XMLList;
var my_sound:XMLList;
var my_total:Number;
var my_itemnum:Number = 0;
var xmlLoader:URLLoader = new URLLoader(); 
xmlLoader.load(new URLRequest("content.xml")); 
xmlLoader.addEventListener(Event.COMPLETE, processXML); 
 
function processXML(e:Event):void { 
 var my_FlashCards:XML = new XML(e.target.data); 
 my_korean=my_FlashCards.flashcard.korean;
 my_english=my_FlashCards.flashcard.english;
 my_actiontype=my_FlashCards.flashcard.actiontype;
 my_total=my_korean.length();
 trace("Korean: "+my_korean);
 trace("English: "+my_english);
 trace("ActionType: "+my_actiontype);
 trace("Total: "+my_total);
 type_mc.gotoAndStop(my_actiontype[my_itemnum]);
 term_txt.text=my_korean[my_itemnum];
} 
//When the language button is pressed down
function mouseDownHandler(event:MouseEvent):void{
 trace(my_english.text[my_itemnum]);
 term_txt.text=my_english.text[my_itemnum];
}
//When the language button is let up
function mouseUpHandler(event:MouseEvent):void{
 term_txt.text=my_korean.text[my_itemnum];
}
language_btn.addEventListener(MouseEvent.MOUSE_DOWN,mouseDownHandler);
language_btn.addEventListener(MouseEvent.MOUSE_UP,mouseUpHandler);
stop();

The issue that I have is that I cannot get my language button to function any more. It says that my value is undefined. My plan is to add remove value to the variable my_itemnum as needed to switch between words and values. Any help would be appreciated.
