我使用ContentResolver获取歌曲列表:

    ContentResolver cr = getContentResolver();

    Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
    String selection = MediaStore.Audio.Media.IS_MUSIC + "!= 0";
    String sortOrder = MediaStore.Audio.Media.TITLE + " ASC";
    Cursor cur = cr.query(uri, null, selection, null, sortOrder);
    int count = 0;

    if(cur != null) {
        count = cur.getCount();
        if(count > 0) {
            while(cur.moveToNext()) {
                songs.add(cur.getString(cur.getColumnIndex(MediaStore.Audio.Media.DATA)));
            }
        }
    }
    cur.close();

然后我尝试使用MediaPlayer播放列表中的第一首歌曲:

MediaPlayer player = new MediaPlayer();
try {
    player.setDataSource(songs.get(0));
} catch (IOException e) {
    e.printStackTrace();
}
player.start();

我收到错误:
