调用外部API不成功，显示的什么执行时间长，我实在解决不了了

Question

下面是我的util
package textview.exam;

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

/**

• Created by fei on 2016/6/16.
  */
  public class Shishinews {
  String httpUrl = "http://apis.baidu.com/songshuxiansheng/news/news";
  String httpArg = "";
  String jsonResult = request(httpUrl, httpArg);
  //System.out.println(jsonResult);

  /**

  • @param urlAll
  • :请求接口
  • @param httpArg
  • :参数

  • @return 返回结果
    */
    public static String request(String httpUrl, String httpArg) {
    BufferedReader reader = null;
    String result = null;
    StringBuffer sbf = new StringBuffer();
    httpUrl = httpUrl + "?" + httpArg;

    try {
    URL url = new URL(httpUrl);
    HttpURLConnection connection = (HttpURLConnection) url
    .openConnection();
    connection.setRequestMethod("GET");
    // 填入apikey到HTTP header
    connection.setRequestProperty("apikey", "f761aa7e1d7b5ebe4******");
    connection.connect();
    InputStream is = connection.getInputStream();
    reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
    String strRead = null;
    while ((strRead = reader.readLine()) != null) {
    sbf.append(strRead);
    sbf.append("\r\n");
    }
    reader.close();
    result = sbf.toString();
    } catch (Exception e) {
    e.printStackTrace();
    }
    return result;
    }

}

下面是我fragment的代码

下面是我AndroidMainfest.xml中的代码

                 //是URL回传超时
                    String httpUrl = "http://apis.baidu.com/songshuxiansheng/news/news?apikey=****";
                    URL myURL = new URL("http://localhost:8888/SwitchDemo/QueryCompany/SubmitBatchTest2.jsp");
        URLConnection ucon = myURL.openConnection();  
        InputStream is = ucon.getInputStream();  
        int size=is.available();
        byte[] buf=new byte[size];
        is.read(buf);
        is.close();
        String outStr=new String(buf,"utf-8");
