在MediaPlayer與SurcaceView播放視頻的時候，若是播放的視頻碼流有誤，使Media Server Died， 這時若是從新釋放MediaPlayer並建立，有時會出現 [SurfaceView] connect: already connected (cur=3, req=3) setVideoSurfaceTexture failed: -22這樣的錯誤（這是在htc上出現的）或者出現 E/MemoryHeapBase(13312): mmap(fd=21, size=0) failed (Invalid argument)（這是在ipad上出現的）

分析緣由應該是surfaceview佔用，與新建立的mediaplayer沒法正常關聯，須要從新建立surfaceview

可行方法

surfaceView.setVisibility(View.GONE);

surfaceView.setVisibility(View.VISIBLE);

這樣就能夠從新建立surfaceview，能夠恢復上面提示的錯誤，正常播放。

參考代碼

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();// 緩衝
    }
   } catch (Exception e) {
    e.printStackTrace();
   }

}
