Answer 1

Try this:

public void removePlaylistMember(Context context, long memberid,
        long mplaylistid) {
    try {
        Uri uri = MediaStore.Audio.Playlists.Members.getContentUri(
                "external", mplaylistid);
        String selection = MediaStore.Audio.Playlists.Members.AUDIO_ID
                + "=?";
        String selectionargs[] = { String.valueOf(memberid) };
        context.getContentResolver().delete(uri, selection, selectionargs);
    } catch (Exception e) {
    }
}
