About Android use webservice many articles, here is a brief look.

Here you first introduced webservice package (Download: Ksoap2.jar ), Why is soap? Long story, soap protocol directly ask of your mother.

The next step is the use of:

The first to have such a url (http: // ip:? Port / project name / ws (the default is ws) / srvmobile (address of the interface) wsdl), if not to be asked back.

This address can be opened in a web page.

For example like this:

 Make do and see.

Many of this page information, including a request necessary for webservice namespace, the method name and parameters needed.

After obtaining this information, you can call webservice in the project to request the data background.

Method:

 SoapObject request = new SoapObject(namespace, methodName);
        // 设置需调用WebService接口需要传入的两个参数mobileCode、userId
        request.addProperty("mobileCode", phoneSec);
        request.addProperty("userId", "");

        //创建SoapSerializationEnvelope 对象，同时指定soap版本号(之前在wsdl中看到的)
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapSerializationEnvelope.VER12);
        envelope.bodyOut = request;//由于是发送请求，所以是设置bodyOut
        envelope.dotNet = true;//由于是.net开发的webservice，所以这里要设置为true

        //你的在网页上可以的打开的WSDL_URI
        HttpTransportSE httpTransportSE = new HttpTransportSE(WSDL_URI);
        httpTransportSE.call(null, envelope);//调用

        // 获取返回的数据
        SoapObject object = (SoapObject) envelope.bodyIn;
        // 获取返回的结果
        result = object.getProperty(0).toString();
        Log.d("debug",result);

The network can request the package at:

Below, you can go back and stick with: Yes, that Constants.URL_NAME_SPACE to change your own.

public class WebServiceUtils {
//Constants.URL_NAME_SPACE; 改成你自己的namespace
    private  final String nameSpace = Constants.URL_NAME_SPACE;
    private SoapObject msg;
    private String url;
    private String methodName;
    private OnCallListener listener;

        this.url = url;
        this.methodName = methodName;
        msg = new SoapObject(nameSpace, this.methodName);

    }

        return listener;

                SoapEnvelope.VER11);
        envelope.bodyOut = msg;
        envelope.dotNet = false;
        HttpTransportSE sendRequest = new HttpTransportSE(url, 10 * 1000);
        envelope.setOutputSoapObject(msg);
        try {
            sendRequest.call(nameSpace + methodName, envelope);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            Log.i("aaa", "webservice错误=" + e.getMessage());
        } catch (XmlPullParserException e) {

            Log.i("aaa", "webservice错误=" + e.getMessage());

        }
        try {
            result = (SoapObject) envelope.bodyIn;
        } catch (Exception e) {
            // TODO Auto-generated catch block
            //Utils.log("webservice错误=" + e.getMessage());
        }
        if (result == null) {
            return "";
        } else {
            return result.getProperty(0).toString();
        }

    }

    /**

    class Work extends AsyncTask<String, Integer, String> {

        @Override

            // TODO Auto-generated method stub
            String resut = call();
            return resut;

                if (result.equals("")) {
                    listener.onPostFail();
                } else {
                    listener.onPostExecute(result);
                }

            }
        }

    }

    /**
     * 回调接口
     */
    public interface OnCallListener {
        /**

        void onPreExecute();

         */
        void onPostExecute(String result);

        /**
         * 请求失败
         */
        void onPostFail();
    }
}

This webservice you can use in your project.

The above WebserviceUtils used as follows:

  WebServiceUtils webServiceUtils = new WebServiceUtils(WSDL_URL, 方法名);         
            String requesttime = String.valueOf(new Date().getTime());
//添加参数
            webServiceUtils.putParam("requesttime", requesttime);
            webServiceUtils.execute(new WebServiceUtils.OnCallListener() {}

Can, use happy!
