在MediaPlayer与SurcaceView播放视频的时候，如果播放的视频码流有误，使Media Server Died， 这时如果重新释放MediaPlayer并创建，有时会出现 [SurfaceView] connect: already connected (cur=3, req=3) setVideoSurfaceTexture failed: -22这样的错误（这是在htc上出现的）或者出现 E/MemoryHeapBase(13312): mmap(fd=21, size=0) failed (Invalid argument)（这是在ipad上出现的）

分析原因应该是surfaceview占用，与新创建的mediaplayer无法正常关联，需要重新创建surfaceview

可行方法

surfaceView.setVisibility(View.GONE);

surfaceView.setVisibility(View.VISIBLE);

这样就可以重新创建surfaceview，可以恢复上面提示的错误，正常播放。

参考代码

private void Replay() {

mediaPlayer.reset();
  mediaPlayer.release();
  mediaPlayer = null;
  surfaceView.setVisibility(View.GONE);
  mediaPlayer = new MediaPlayer();
  mediaPlayer.setOnErrorListener(mErrorListener);
  mediaPlayer.setOnPreparedListener(new PrepareListener(0));
  mediaPlayer.setOnVideoSizeChangedListener(new VideoSizeListener());
  mediaPlayer.setOnCompletionListener(mOnCompletionListener);
  surfaceView.setVisibility(View.VISIBLE);

    try {
    if (mediaPlayer != null) {
     mediaPlayer.reset();
     handlerUI.sendEmptyMessageDelayed(HIDESURFACE, 100);
     mediaPlayer.setDataSource(strUrl);
     mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
     mediaPlayer.setDisplay(surfaceHolder);
     mediaPlayer.prepareAsync();// 缓冲
    }
   } catch (Exception e) {
    e.printStackTrace();
   }

}
