推荐答案

检查this出。我用这个函数来提取从YouTube视频的直接下载链接（它返回一个链接数组）。所有你需要做的就是用这个来获取视频（而不是手机版！）的HTML code：

Check this out. I use this function to extract the direct download links from a youtube video (it returns an array with links). All you need to do is to get the html code of the video (not the mobile version!) using this:

                 // url = youtube link (e.g. http://www.youtube.com/watch?v=fJ9rUzIMcZQ)
  public String DownloadText(String url) throws IOException{
      String userAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:8.0.1)";
      HttpClient client = new DefaultHttpClient();
      client.getParams().setParameter(CoreProtocolPNames.USER_AGENT, userAgent);

      HttpGet request = new HttpGet(url);
      HttpResponse response = client.execute(request);

      String html = "";
      InputStream in = response.getEntity().getContent();
      BufferedReader reader = new BufferedReader(new InputStreamReader(in));
      StringBuilder str = new StringBuilder();
      String line = null;
      while((line = reader.readLine()) != null)
      {
          str.append(line);
      }
      in.close();
      html = str.toString();

      return html;
    }
