Hey everyone i am trying to access a simple web service that add two digits , now i know many have asked this question but i have seriously tried nearly every solution i've seen , most of them were correct the namespace , soap address etc , but i mine is absolutely correct . I m going crazy because i've been at this for the last 8 hours and no success -_- . So plzz help anyone. First of all i am try this for the first time so i really don't have a lot of knowledge about soap , the code u see , i picked most of it . But i also understand most of it.

package com.example.usingaddservice;

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;

public class MainActivity extends Activity 
{
    /** Called when the activity is first created. */
    private static final String SOAP_ACTION = "http://tempuri.org/add";

    private static final String OPERATION_NAME = "add";// your webservice web method name

    private static final String WSDL_TARGET_NAMESPACE = "http://tempuri.org/";

    private static final String SOAP_ADDRESS = "http://10.0.2.2:42875/Service.asmx";

    EditText e1,e2;
    Button button;
    TextView ans;
    int a,b;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);                

        e1 = (EditText) findViewById(R.id.editText1);
        e2 = (EditText) findViewById(R.id.editText2);
        ans = (TextView) findViewById(R.id.ans);

        button=(Button)findViewById(R.id.button1);

        button.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                a = Integer.parseInt(e1.getText().toString());
                b = Integer.parseInt(e2.getText().toString());
                SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE,OPERATION_NAME);

                //propertyInfo.type = PropertyInfo.INTEGER_CLASS;

                        propertyInfo.setType(Integer.class);
                        request.addProperty(propertyInfo);
                        propertyInfo=new PropertyInfo();
                        propertyInfo.setName("b");
                        propertyInfo.setValue(b);
                        propertyInfo.setType(Integer.class);
                        request.addProperty(propertyInfo);

                SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER12);
                envelope.dotNet = true;

                envelope.setOutputSoapObject(request);

                HttpTransportSE httpTransport = new HttpTransportSE(SOAP_ADDRESS);
                try{

                httpTransport.call(SOAP_ACTION, envelope);                    
                Object response = envelope.getResponse();                    
                ans.setText(response.toString());                    
                }  catch (Exception e)   {
                              Log.d("Errror is", e.getClass()+" "+e.getMessage());                    
                }
