Querying for album art always returns No entry for content://media/external/audio/albumart/31726


So I've been trying this for some time now. To get the album art for an mp3 file and displaying it on its respective ImageView and I am using the uri("content://media/external/audio/albumart")

This is my method for getting the album art

    public Bitmap getAlbumArt(long idAlbum){
    Bitmap bitmap = null;

    try{
        final Uri sArtworkUri = Uri.parse("content://media/external/audio/albumart");
        Uri uri = ContentUris.withAppendedId(sArtworkUri, idAlbum);
        ParcelFileDescriptor parcelFileDescriptor = getContext().getContentResolver().openFileDescriptor(uri,"r");
        if (parcelFileDescriptor != null){
            FileDescriptor fileDescriptor = parcelFileDescriptor.getFileDescriptor();
            bitmap = BitmapFactory.decodeFileDescriptor(fileDescriptor);
        }

    }catch (Exception e){
        e.printStackTrace();
    }
    return bitmap;
    } 

and this method always returns

java.io.FileNotFoundException: No entry for content://media/external/audio/albumart/31726

where the 31726 is the album id.

Since I'm catching this exception and I set it to a default Album art if it returns null, every mp3 has its ImageView set to the default album art. I am using my Samsung Galaxy s3 to run the application and my device runs android 4.2.2 JellyBean. Please someone help me getting this right.

This is how I request the album id

    Uri musicUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
    String[] columns = {
            MediaStore.Audio.Media.TITLE,
            MediaStore.Audio.Media.ARTIST,
            MediaStore.Audio.Albums._ID,
            MediaStore.Audio.Media.DATA
    };

    String where = MediaStore.Audio.Media.IS_MUSIC + "=1";

    Cursor musicCursor = usicResolver.query(musicUri,columns,where,null,    null);

Then in an if loop with condition

    if(musicCursor.moveToFirst()){
    int albumId = musicCursor.getColumnIndex
                (MediaStore.Audio.Albums._ID);
    do{
          long idAlbum = musicCursor.getLong(albumId);

          //Then i send it to my above method getAlbumArt
          Bitmap songAlbumArt = getAlbumArt(idAlbum);

      }while(musicCursor.moveToNext());

     }

Solution

  • This is how I query the cover art path from the album id:

    private static String getCoverArtPath(long albumId, Context context) {
    
        Cursor albumCursor = context.getContentResolver().query(
                MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI,
                new String[]{MediaStore.Audio.Albums.ALBUM_ART},
                MediaStore.Audio.Albums._ID + " = ?",
                new String[]{Long.toString(albumId)},
                null
        );
        boolean queryResult = albumCursor.moveToFirst();
        String result = null;
        if (queryResult) {
            result = albumCursor.getString(0);
        }
        albumCursor.close();
        return result;
    }
    

    You can get the Bitmap from the BitmapFactory using the path returned from the method above:

    BitmapFactory.decodeFile(coverArtPath);
