我是 android 新手，我正在尝试使用 jsoup 从网站获取数据，但是当我执行 get() 方法时没有任何反应。这是我的代码：

static final String BLOG_URL = "http://xjaphx.wordpress.com/";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_html_parser);
    // Show the Up button in the action bar.
    setupActionBar();


      // process
    new DownloadFilesTask().execute();
}

私有类 DownloadFilesTask 扩展 AsyncTask {

     String result = "";
    @Override
    protected String doInBackground(Void... params) {

            // get html document structure
            Document document=null;
            try {
                document = Jsoup.connect(BLOG_URL).get();

            // selector query
            Elements nodeBlogStats = document.select("div#blog-stats ul li");
            // check results
            if(nodeBlogStats.size() > 0) {
                // get value
                result = nodeBlogStats.get(0).text();
            }
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            // return


            return null;
    }


    protected void onPostExecute()
     {

    TextView article = (TextView)findViewById(R.id.textView1);

    article.setText(result);

}

}

这是我的 LogCat 日志：
