Question

I am consuming tempconvert web services but it does not give any result just show blank screen.

Does that mean my app does not access the web services, or i have to some setting so it will connect to URL, i am using ksoap2 2.6.5 .

this is my code

package com.example.webservice2;

import android.os.Bundle;
import android.widget.TextView;
import android.app.Activity;
import org.ksoap2.*;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;

public class WebService extends Activity {

    private final String SOAP_ACTION = "http://tempuri.org/CelsiusToFahrenheit";
    private final String METHOD_NAME = "CelsiusToFahrenheit";
    private final String NAMESPACE = "http://tempuri.org/";
    private final String URL = "http://www.w3schools.com/webservices/tempconvert.asmx";

    TextView tv;

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

        tv = (TextView) findViewById(R.id.tv);

        SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);
        Request.addProperty("celsius", "32");

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);
        envelope.dotNet = true;
        envelope.setOutputSoapObject(Request);

        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

        try {
            androidHttpTransport.call(SOAP_ACTION, envelope);
            SoapPrimitive response = (SoapPrimitive) envelope.getResponse();

            tv.setText("status:" + response);

        } catch (Exception e) {
            e.printStackTrace();
        }
