Android - Videoview URL HttpURLConnection

Question

我有一个活动（活动A），可以调用另一个从URL（视频视频）加载视频的活动。当我回到活动A，我可以去活动B，我有一个代码执行与HttpURLConnection的请求。问题是如果我去活动视频并加载Videoview，请求活动B返回一个空响应。

如果我更改活动视频并删除视频视图，它工作良好。

活动视频：

String urlVideo = getIntent().getStringExtra("URL_TRAILER");  
    Uri uri = Uri.parse(urlVideo); 
    videoView = (VideoView)findViewById(R.id.myvideoview);  
    MediaController mc = new MediaController(this); 
    mc.setAnchorView(videoView); 
    mc.setMediaPlayer(videoView); 
    videoView.setMediaController(mc); 
    videoView.setVideoURI(uri); 
    videoView.start(); 

HttpURLConnection的

 HttpURLConnection conn = (HttpURLConnection) url.openConnection(); 
    conn.setDefaultUseCaches(false); 
    conn.setUseCaches(false); 
    conn.setReadTimeout(15000); 
    conn.setConnectTimeout(15000); 
    conn.setRequestMethod("POST"); 
    conn.setDoInput(true); 
    conn.setDoOutput(true); 

    int responseCode = conn.getResponseCode(); 

    if (responseCode == HttpsURLConnection.HTTP_OK) { 
     String line; 
     BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream())); 
     while ((line = br.readLine()) != null) { 
      response += line; 
     } 
    } else { 
     response = ""; 

    }

我找到了解决方案，使用的HttpClient和Htt的pPost而不是HttpURLConnection。

我不知道HttpURLConnection有什么问题。
