int b=getContentResolver().update(MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI, values_art,MediaStore.Audio.Albums.ALBUM_ID + "=?", new String[]{album_id});

}

Answer 1

You must delete the previous artwork first (if it already exist):

Uri sArtworkUri = Uri.parse("content://media/external/audio/albumart");    
int deleted = getContentResolver().delete(ContentUris.withAppendedId(sArtworkUri, album_id), null, null);

and then insert it again:

ContentValues values = new ContentValues();
values.put("album_id", album_id);
values.put("_data", file_url);
Uri num_updates = getContentResolver().insert(sArtworkUri, values);
