Apps Android AlbumArt

[vag]

I am developing a sort of media player for android, want to get Album Art, and use this code.

Uri sArtworkUri = Uri.parse("content://media/external/audio/albumart");
Uri uri = ContentUris.withAppendedId(sArtworkUri, album_id);
ContentResolver res = context.getContentResolver();
try {
in = res.openInputStream(uri);
} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
Bitmap artwork = BitmapFactory.decodeStream(in);
But I get FileNotfoundExeption, and artwork sets to null(

Here is the LogCat
