老师，为什么mMediaPlayer.start();播放器没有播放；但是加了Thread.sleep(3000);延时后就正常了

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //音乐播放
        MediaPlayerManager mediaPlayerManager =  new MediaPlayerManager();
        AssetFileDescriptor fileDescriptor=getResources().openRawResourceFd(R.raw.lovingstrangers);
        mediaPlayerManager.startPlay(fileDescriptor);
        try {
            Thread.sleep(3000);
        }catch (Exception e){
            LogUtils.e(e.toString());
            e.printStackTrace();
        }
    }
