I got problem on how I connected to web service using ksoap2
my code :
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.*;
import org.ksoap2.transport.HttpTransportSE;
import android.widget.TextView;
public class FirstScreen extends Activity {
private static final String SOAP_ACTION = "http://tempuri.org/CelsiusToFahrenheit";
private static final String METHOD_NAME = "CelsiusToFahrenheit";
private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://www.w3schools.com/webservices/tempconvert.asmx";
TextView tv;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_first_screen);
tv= (TextView)findViewById(R.id.TextView01);
SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);
Request.addProperty("Celsius", "32");
SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER10);
soapEnvelope.dotNet =true;
soapEnvelope.setOutputSoapObject(Request);
HttpTransportSE bah = new HttpTransportSE(URL);
try
{
bah.call(SOAP_ACTION, soapEnvelope);
SoapPrimitive resultString = (SoapPrimitive)soapEnvelope.getResponse();
tv.setText("status: " + resultString);
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
it says Application MyTest (process com.falafel.mytest)) has stopped unexpectedly!! 🙁
my error:

Any Help would be appriciated, thank you!
Have you done it
Project > Properties > Java Build Path > Order and Export > and finally, checkmark your imported KSOAP2 library.
Also, don’t consume a webservice on UI thread, consider a service or AsyncTask
