的AsyncTask＃1时发生错误，执行doInBackground（）

Question

这里是我的代码和日志信息

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.raspored); 

    Bundle bundle = getIntent().getExtras(); 
    url = bundle.getString("url"); 
    new FetchWebsiteData().execute(); 
} 


private class FetchWebsiteData extends AsyncTask<Void, Void, Void> { 
    String eles = ""; 

    /*@Override 
    protected void onPreExecute() { 
     super.onPreExecute(); 
     mProgressDialog = new ProgressDialog(Raspored.this); 
     mProgressDialog.setMessage("Loading..."); 
     mProgressDialog.setIndeterminate(false); 
     mProgressDialog.show(); 
    }*/ 

    @Override 
    protected Void doInBackground(Void... params) { 
     try { 
      // Connect to website 
      Document document = Jsoup.connect(url).get(); 
      // Get the html document title 
      //websiteTitle = document.title(); 
      Element elementsByTag = document.body(); 
      Element tablica = elementsByTag.getElementsByTag("table").get(9).getElementsByTag("td").get(4); 
      Elements redak = tablica.getElementsByTag("ul"); 
      eles = redak.text().toString(); 

     } catch (IOException e) 
     { 
      e.printStackTrace(); 
     } 
     return null; 
    } 

    @Override 
    protected void onPostExecute(Void result) { 
     // Set title into TextView 
     TextView txttitle = (TextView) findViewById(R.id.tbl_txt); 
     txttitle.setMovementMethod(new ScrollingMovementMethod()); 
     //txttitle.setText(websiteTitle + "\n" + eles); 
     String ele = eles.replace(" ", "\n"); 
     arr_linkText.add(ele); 
     for(String temp : arr_linkText) { 
      txttitle.append(temp); 
     }  
     //mProgressDialog.dismiss(); 
    } 

    } 
}

什么是这里的问题？

你确定jsoup jar是在类路径吗？ 确保jsoup jar已添加到您的apk中。
