How to preview image using xml gallery in android?-Collection of common programming errors

I try to make a simple XML gallery in android platform, but I get an error that says:

Error #2044: Unhandled IOErrorEvent:. text=Error #2035: URL Not Found.

I’m sure that the file location is in the right place /mnt/sdcard/SketchCraft/MyDrawing 1.png.

This is my XML:

 
    
       
          /mnt/sdcard/SketchCraft/MyDrawing 1.png
       
    

This is my actionscript:

 import flash.net.URLLoader;
 import flash.events.Event;
 import flash.display.Loader;
 import flash.net.URLRequest;

 var xmlRequest:URLRequest = new URLRequest("XMLcth.xml");
 var xmlLoader:URLLoader = new URLLoader(xmlRequest);
 var imgData:XML;
 var imageLoader:Loader;
 var rawImage:String;

 var imgNum:Number = 0;

 xmlLoader.addEventListener(Event.COMPLETE, xmlLoaded);

 function xmlLoaded(event:Event):void{
    imgData= new XML(event.target.data);
    rawImage = imgData.image[imgNum].imgURL;
    imageLoader =new Loader();
    imageLoader.load(new URLRequest(rawImage));
    mc_image.addChild(imageLoader);
 }
