How to access nook gallery with Adobe Air for Android - Nook Color Android Development

So, I have an application that I'm doing in Adobe air that lets a user upload an image from their nook. Right now I have this code in AS3:
Code:
var newbitmap:Bitmap;
var loadInfo : LoaderInfo;
var puzzBitmap : Bitmap;
var fileReference:FileReference; //declare file
var loader:Loader = new Loader();
browsebutton.addEventListener(MouseEvent.CLICK, uploadstuff)
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, imageLoaded);
function uploadstuff(e:MouseEvent):void
{
fileReference = new FileReference();
fileReference.addEventListener(Event.SELECT, selectHandler);
fileReference.addEventListener(Event.COMPLETE, completeHandler);
var fileFilter:FileFilter = new FileFilter("Images","*.jpg;*.jpeg;*.gif;*.png;*.bmp;");
fileReference.browse([fileFilter]);
}
function selectHandler(event:Event):void
{
fileReference.load();
}
function completeHandler(event:Event):void
{
loader.loadBytes(fileReference.data);
//addChild(loader);
}
function imageLoaded(event : Event):void
{
loadInfo = event.target as LoaderInfo;
if(loadInfo != null)
{
var bitmap : Bitmap = loadInfo.content as Bitmap;
var sourceData:BitmapData = bitmap.bitmapData;
puzzBitmap = new Bitmap(sourceData);
var matrix:Matrix = new Matrix();
matrix.scale(450/puzzBitmap.width,300/puzzBitmap.height);
var smallBMD:BitmapData = new BitmapData(450, 300, true, 0x000000);
smallBMD.draw(puzzBitmap, matrix, null, null, null, true);
newbitmap = new Bitmap(smallBMD, PixelSnapping.NEVER, true);
puzzBitmap.width=450;
puzzBitmap.height=300;
puzzBitmap.x=260;
puzzBitmap.y=147.5;
addChild(puzzBitmap);
}
}
Now on my laptop this works fine, it lets me browse through my folders and select an image to upload. However, when I port it to nook, hitting browse does bring up a window but it just says "no files found". It doesn't even show me the folder so I an browse the folders and find an image. So nook's filesystem works differently from my laptops where file browsing doesn't work. Any ideas how to do file browsing or access the gallery directly on the nook?
