android如何实现利用sendpost方法同时向两个地址发起网络请求

public static String sendPost(String url, String params1)
{
DataOutputStream dos= null;
BufferedReader in = null;
String result = null;
String end = "\r\n";
String twoHyphens = "--";
String boundary = "******";
try
{
URL myFileUrl =new URL(url);
HttpURLConnection conn = null;
conn = (HttpURLConnection) myFileUrl.openConnection();
conn.setRequestProperty("accept", "*/*");
conn.setRequestProperty("connection", "Keep-Alive");
conn.setRequestProperty("user-agent","Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)");
conn.setRequestProperty("Content-Type","multipart/form-data;boundary=" + boundary);
conn.setDoOutput(true);
conn.setDoInput(true);
dos = new DataOutputStream(conn.getOutputStream());

        dos.writeBytes(twoHyphens + boundary + end);
        dos.writeBytes("Content-Disposition: form-data; name=\"content1\"\r\n");
        dos.writeBytes(end);          
        dos.writeBytes(params1);          
        dos.writeBytes(end);
        dos.writeBytes(twoHyphens + boundary + twoHyphens + end);



        dos.flush();        


        in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
        String line;
        while ((line = in.readLine()) != null)
        {
            result = line;
            System.out.println(result+"xubinxubinxubin");
        }
    }
    catch (Exception e)
    {
        System.out.println("uddascd" + e);
        e.printStackTrace();
        result = "weikaiqi";
    }

    finally
    {
        try
        {
            if (dos != null)
            {
                dos.close();
            }
            if (in != null)
            {
                in.close();
            }
        }
        catch (IOException ex)
        {
            ex.printStackTrace();
        }
    }
    return result;
}

开启另外一条线程就可以了

再开一个线程，在那里发送就行
