MP3에서 albumart 뽑기

안드로이드 어플에서 앨범정보는 참 쉽게 가져올수 있다..

album art라는걸로 검색해왔다면은 이미 앨범정보쯤은 가져왔을건데..

album art만 현재 못가져왔을것이다..

정보가 저장된곳이 다르댄다;;

아래대로 하면은 가져올수 있다.

String[] cols = new String[] {
            MediaStore.Audio.Albums._ID,
            MediaStore.Audio.Albums.ALBUM_ART
    };

Cursor cur = getContentResolver().query(
                 MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI,
                 cols , null , null, null);
   cur.moveToPosition(pos);  
    int idNum = cur.getInt(0);
    Bitmap album_art = getBitmapImage( idNum,200, 200);
    mAlbumArt.setImageBitmap(album_art);


//안사나 안펍에 있는 함수 퍼옴
