尝试从YouTube获取数据时Android崩溃了？

我得到了这个片段，它应该为youtube上某些视频的标题提供烘烤。尝试从YouTube获取数据时Android崩溃了？

public static void getVids() { 
     try { 
      YouTubeService myService = new YouTubeService("mycompany-myapp-1"); 
      String myFeed = "http://gdata.youtube.com/feeds/videos?start-index=1&max-results=25&vq=lizards&oi=spell"; 
      printVideoFeed(myService, myFeed); 
     } catch (IOException ex) { 
      Toast toast = Toast.makeText(null, "Error "+ex.toString(), 5000); 
      toast.show(); 
     } catch (ServiceException ex) { 
      Toast toast = Toast.makeText(null, "Error "+ex.toString(), 5000); 
      toast.show(); 
     } 
    } 

    private static void printVideoFeed(YouTubeService service, String feedUrl) throws IOException, ServiceException { 
     VideoFeed videoFeed = service.getFeed(new URL(feedUrl), VideoFeed.class); 
     List<VideoEntry> allVideos = videoFeed.getEntries(); 
     Iterator<VideoEntry> itAllVideos = allVideos.iterator(); 
     String Titles = ""; 
     while (itAllVideos.hasNext()){ 
      VideoEntry oneVideo = itAllVideos.next(); 
      TextConstruct oneVideoTitle = oneVideo.getTitle(); 
      Titles = Titles + " | " + oneVideoTitle.toString(); 
     } 

     Toast toast = Toast.makeText(null, "Working! " + Titles , 5000); 
     toast.show(); 

    }

但是，当我执行它时崩溃。这里的logcat中这样说：

你觉得可能是什么问题？

我有类似的问题。解决方案应该是用发现的那个Java库来代替你的JavaMail库（用于Android的JavaMail here）。

嗯...替换，同样的问题。 :( – Roger

啊，这很糟糕。在这种情况下，我会考虑使用[GData for Android]（http://code.google.com/p/google-api-java-client/）。 –

谢谢，你拯救我的一天:) – CodeNinja

直接来自YouTube API团队：“我的理解是Java Java数据客户端库目前不兼容Android运行时环境。”

This link是我找到答案以及您看到的错误消息。
