Mediastore albums and media columns

Too retrieve the album id i use:

String SONG_ALBUMID  = MediaStore.Audio.Albums.ALBUM_ID;

But what is the difference between MediaStore.Audio.Albums.ALBUM_ID and MediaStore.Audio.Media.ALBUM_ID

Thanks,

Here are 2 approaches: (include the requested columns in your resolver.query)

     public String getalbum_id(Cursor pcursor) {
    int album_col = pcursor
            .getColumnIndexOrThrow(MediaStore.Audio.Media.ALBUM_ID);
    String album_id = pcursor.getString(album_col);

    if (album_id.length() > 0) {
        return album_id;
    } else {
        return "";
    }
}

public String getAlbumIdfromPath(Context context, String datapath) {
    ContentResolver cr = context.getContentResolver();
    final String _id = MediaStore.Audio.Media._ID;
    final String path = MediaStore.Audio.Media.DATA;
    final String album_id = MediaStore.Audio.Media.ALBUM_ID;
    final String[] columns = {_id, album_id};
    final String[] trackpath = {"%" + datapath + "%"};
    String where = path + " LIKE ?";
    String stralbum_id = null;
    Cursor crs = cr.query(uri, columns, where, trackpath, null);
    if (crs != null && crs.moveToFirst()) {
        stralbum_id = crs.getString(crs.getColumnIndexOrThrow(album_id));
        crs.close();
    }
    return stralbum_id;
}

now to display, I have posted previously but I use the Gilde library. It does all the hard work.

            //  loading album cover using Glide library
        String artist_id = (c.getString(c
                .getColumnIndex(MediaStore.Audio.Artists._ID)));
        Cursor albs = albums.getArtistsAlbumcursor(mContext, artist_id);
        String stralbumId=null;
        if(albs!=null && albs.moveToFirst()){
           stralbumId= albs.getString(albs.getColumnIndexOrThrow(MediaStore.Audio.Media.ALBUM_ID));
        }
        Uri ImageUrl = plist.getAlbumUri(mContext, stralbumId);
        if (ImageUrl != null) {
            Glide.with(mContext)
                    .asBitmap()
                    .load(ImageUrl)
                    .into(image);
        }
    }

where getAlbumuri is:

     public Uri getAlbumUri(Context mContext,String album_id){
    if(mContext!=null) {
        Uri sArtworkUri = Uri.parse("content://media/external/audio/albumart");
        Uri imageUri = Uri.withAppendedPath(sArtworkUri, String.valueOf(album_id));
        return imageUri;
    }
    return null;
}

Include the following in your module build.gradle

    implementation 'com.github.bumptech.glide:glide:4.5.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.7.1'

   private final Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
