android连接WebService不成功，求助

初学Android，很多不懂，各位勿取笑！
低级问题，可能看了都笑，但希望各位不吝教点：
错误提示如下
“java.net.ConnectException: failed to connect to localhost/127.0.0.1 (port 54311) after 20000ms: isConnected failed: ECONNREFUSED (Connection refused)”
服务代码，很简单：



[WebService(Namespace = "http://tempuri.org/")]

    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

    [ToolboxItem(false)]

    // 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消对下行的注释。

    // [System.Web.Script.Services.ScriptService]

    public class Service1 : System.Web.Services.WebService

    {



        [WebMethod]

        public string HelloWorld()

        {

            return "Hello World";

        }

        [WebMethod(Description = "返回字符串")]

        public string GetString()

        {

            return "return string";

        }

        [WebMethod(Description = "两值求合")]

        public double GetSum(double a, double b)

        {

            return a + b;

        }

    }

Android代码



String url="http://localhost:54311/Service1.asmx";  

String nameSpace = "http://localhost:54311/";     

String methodName = "GetString";

请求WebService



protected Object CallWebService(){   

	                String SOAP_ACTION = nameSpace + methodName;    

	                //创建SoapObject实例   

	                SoapObject request=new SoapObject(nameSpace,methodName);   

	                //生成调用web service方法的soap请求消息   

	                SoapSerializationEnvelope envelope=new SoapSerializationEnvelope(SoapEnvelope.VER11);   

	                //设置.net web service   

	                envelope.dotNet=true;   

	                envelope.bodyOut=request;

	                (new MarshalBase64()).register(envelope);

	                //发送请求   

	                //envelope.setOutputSoapObject(request);   

	                //请求参数   

	                if(params != null && !params.isEmpty() ){   

	                        for(Iterator it=params.entrySet().iterator();it.hasNext();){   

	                                Map.Entry e=(Entry) it.next();   

	                                request.addProperty(e.getKey().toString(),e.getValue());   

	                        }   

	                }   

	                //   

	                HttpTransportSE htse = new HttpTransportSE(url);

	                SoapObject result=null;   

	                try{   

	                        //web service请求   

	                        //androidHttpTrandsport.call(SOAP_ACTION, envelope);

	                	htse.call(SOAP_ACTION, envelope);

	                        //得到返回结果   

	                        result=(SoapObject) envelope.getResponse();   

	                }catch(Exception ex){   

	                        ex.printStackTrace();   

	                }   

	                return result;   

	                   

	        }
