problem accessing array objects in android

Question

I am trying to display a list of containing images and text that i retrieved from a website. I have used the adapter. But the problem is that i couldnt access the array objects that i have declared. I am rather confused what the error is. I couldnt get the list but i am getting a blank screen...Here's the code...Plz help me....

public class SongsAdapter extends SimpleAdapter{
static List<HashMap<String,String>> songsListWeb;
Context context;
LayoutInflater inflater;
public SongsAdapter(Context context,List<HashMap<String,String>> imgListWeb,int layout,String[] from,int[] to,LayoutInflater inflater) {
    super(context,songsListWeb,layout,from,to);
    this.songsListWeb=songsListWeb;
    this.context=context;
    this.inflater=inflater;
    // TODO Auto-generated constructor stub
}
@Override
public View getView(int postition,View convertView,ViewGroup parent)throws java.lang.OutOfMemoryError{
    try {
         View rowView = ((LayoutInflater) 

inflater).inflate(R.layout.row,null); ImageView images=(ImageView)rowView.findViewById(R.id.image); TextView tvTitle=(TextView)rowView.findViewById(R.id.text1); TextView tvAlbum=(TextView)rowView.findViewById(R.id.text2); TextView tvArtist=(TextView)rowView.findViewById(R.id.text3); HashMap songsHash=songsListWeb.get(postition); String path=songsHash.get("path"); String title=songsHash.get("title"); String album=songsHash.get("album"); String artist=songsHash.get("artist"); String imgPath=path;
final ImageView imageView = (ImageView) rowView.findViewById(R.id.image); AsyncImageLoaderv asyncImageLoader=new AsyncImageLoaderv(); Bitmap cachedImage = asyncImageLoader.loadDrawable(imgPath, new AsyncImageLoaderv.ImageCallback() { public void imageLoaded(Bitmap imageDrawable, String imageUrl) {

            imageView.setImageBitmap(imageDrawable);
        }
        });

    imageView.setImageBitmap(cachedImage);

    tvTitle.setText(title);
    tvAlbum.setText(album);
    tvArtist.setText(artist);
    return rowView;
    }
    catch(Exception e){
        Log.e("err",e.toString());
    }
    return null;
}
public static Bitmap loadImageFromUrl(String url) {
    InputStream inputStream;Bitmap b;
try {
    inputStream = (InputStream) new URL(url).getContent();
    BitmapFactory.Options bpo=  new BitmapFactory.Options();
    bpo.inSampleSize=2;
     b=BitmapFactory.decodeStream(inputStream, null,bpo );
     return b;
} catch (IOException e) {
        throw new RuntimeException(e);
    }
}
