为什么android mediaPlayer"onBufferingUpdate"运作不佳 [英] Why android mediaPlayer "onBufferingUpdate" is not work well

问题描述

 mPlayer.setOnPreparedListener(new OnPreparedListener() {
  @Override
  public void onPrepared(MediaPlayer mp) {
    hideBgAndLoadProcess();
    if (mPlayer.isPlaying()) {
      mPlayer.stop();
    }
    Log.e("TAG", "onPrepared is called");
    mPlayer.start();
  }
});
mPlayer.setOnBufferingUpdateListener(new OnBufferingUpdateListener() {
  @Override
  public void onBufferingUpdate(MediaPlayer mp, int percent) {
    Log.e("TAG", "percent is :" + percent);
    sbProgress.setSecondaryProgress(percent);
    int currentProgress =
        sbProgress.getMax() * mPlayer.getCurrentPosition() / mPlayer.getDuration();
    Log.e(currentProgress + "% play", percent + "% buffer");
  }
});

myPlayer设置了"onBufferingUpdateListener"，但效果不佳，有人知道为什么吗?在播放myPlayer时，似乎从未调用过"onBufferingUpdate"，因为未打印日志.

myPlayer set the "onBufferingUpdateListener" but it not work well,anybody knows why? when myPlayer is playing ,the "onBufferingUpdate" seems never called because the Log is not print.
