在Android中使用Jsoup

我在android應用程序中有一個簡單的代碼，我在其中使用一個簡單的jsoup代碼連接到鏈接並獲得在線廣播的標題。但是當我點擊播放按鈕時，我的應用程序退出崩潰。這是我的onClick動作：在Android中使用Jsoup

btnPlay.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      progressDialog.show(); 

      Document doc = null; 
      try { 
       doc = Jsoup.connect("http://info.radiostyle.ru/inc/getinfo.php?getcurentsong=20383&mount=lezgifm").get(); 
       String s = doc.body().text(); 
       System.out.println(s); 
       lblMusicName.setText(s); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 

      new Thread(new Runnable() { 

       @Override 
       public void run() { 

        if (radioBtn128.isChecked()) 
         url = "http://stream4.radiostyle.ru:8004/lezgifm"; 
        else if (radioBtn32.isChecked()) 
         url = "http://stream0.radiostyle.ru:8000/lezgifm"; 
        setStream(url); 
        isPlaying = true; 
        progressDialog.dismiss(); 
       } 
      }).start();    
     } 
    });

當我嘗試調試時，調試器正在循環文檔doc = null點。哪裏不對？

UPDATE：堆棧跟蹤異常：

是否有打印的任何異常？你可以顯示logcat嗎？ :) –

觀看更新，請！ –

因此，在另一個線程中執行網絡內容。你永遠不會想在UI線程上長時間運行任何事情。 –
