如何解决Networkonmainthread异常

我打电话的房地产网站的Web服务，并为我建立了我自己的方法的所有.. 我制定了执行方法中，我将设置我的网址按我的要求如下：

I call a web service of real estate web site and for that i built my own method's and all.. I develop a execute method in which i will set my url as per my requirement as below :

 public void Execute(RequestMethod method) throws Exception
    {
        switch(method) {
            case GET:
            {
                //add parameters
                String combinedParams = "";
                if(!params.isEmpty()){
                    combinedParams += "?";
                    for(NameValuePair p : params)
                    {
                        String paramString = p.getName() + "=" + URLEncoder.encode(p.getValue(),"UTF-8");
                        if(combinedParams.length() > 1)
                        {
                            combinedParams  +=  "&" + paramString;
                        }
                        else
                        {
                            combinedParams += paramString;
                        }
                    }
                }

                HttpGet request = new HttpGet(url + combinedParams);

                //add headers
                for(NameValuePair h : headers)
                {
                    request.addHeader(h.getName(), h.getValue());
                }

                **executeRequest(request, url);** // This throws an exception
                break;
            }
            case POST:
            {
                HttpPost request = new HttpPost(url);

                //add headers
                for(NameValuePair h : headers)
                {
                    request.addHeader(h.getName(), h.getValue());
                }

                if(!params.isEmpty()){
                    request.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));
                }

                executeRequest(request, url);
                break;
            }
        }
    }

在GET的情况下，我利用发送HTTPGET请求与我想要的网址，但在上主线程异常时网络生成的。

In get case , i send the request using httpget with my desired url but at that time network on main thread exception is generated.
