Par exemple
D'abord, supprimer les lignes que vous souhaitez mettre à jour
Uri albumArtUri = Uri.parse("content://media/external/audio/albumart");
ctx.getContentResolver().delete(ContentUris.withAppendedId(albumArtUri, 16), null, null);
ctx.getContentResolver().delete(ContentUris.withAppendedId(albumArtUri, 25), null, null);
ctx.getContentResolver().delete(ContentUris.withAppendedId(albumArtUri, 24), null, null);
ctx.getContentResolver().delete(ContentUris.withAppendedId(albumArtUri, 30), null, null);
ctx.getContentResolver().delete(ContentUris.withAppendedId(albumArtUri, 14), null, null);
