如何将曲目添加到Android 29的播放列表

如何解决如何将曲目添加到Android 29的播放列表

我有以下代码，可以正常使用，将歌曲添加到播放列表。但是，它在Android 29中不再起作用。似乎光标为null或其中没有任何元素。

public static void addToPlaylist(ContentResolver resolver,int audioId,long playlistId) {

    String[] cols = new String[] {
            MediaStore.Audio.Playlists.Members.PLAYLIST_ID,MediaStore.Audio.Playlists.Members.TITLE,};
    Uri uri = MediaStore.Audio.Playlists.Members.getContentUri("external",playlistId);
    Cursor cur = resolver.query(uri,cols,null,null);
    int base = 0;
    if( cur != null && cur.movetoFirst() ) {
        base = cur.getInt(0);
        cur.close();

        ContentValues values = new ContentValues();
        values.put(MediaStore.Audio.Playlists.Members.PLAY_ORDER,Integer.valueOf(base + audioId));
        values.put(MediaStore.Audio.Playlists.Members.AUdio_ID,audioId);
        resolver.delete(uri,MediaStore.Audio.Playlists.Members.AUdio_ID + " = " + audioId,null);
        resolver.insert(uri,values);
    }
}
