import android.widget.TextView;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import org.ksoap2.serialization.SoapPrimitive;
import org.xmlpull.v1.XmlPullParserException;

public class WSActivity extends Activity {
    /** Called when the activity is first created. */
	
	private static final String SOAP_ACTION = "http://tempuri.org/GetDepCode";
	private static final String METHOD_NAME = "GetDepCode";
	private static final String NAMESPACE = "http://tempuri.org/";
	private static final String URL = "http://localhost:100/Service.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);
        PropertyInfo pi = new PropertyInfo();
        pi.setName("QCode");
        pi.setValue("0473");
        pi.setType(PropertyInfo.INTEGER_CLASS);

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
		//envelope.dotNet = true;
		envelope.setOutputSoapObject(request);
		
		
		
		HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
		androidHttpTransport.debug = true;
		try {	
			androidHttpTransport.call(SOAP_ACTION, envelope);
			SoapPrimitive sp=SoapPrimitive)envelope.getResponse(); 
			tv.setText("Value:"+sp);
			} 
		catch (IOException e) {e.printStackTrace();	}
                catch (XmlPullParserException e) {e.printStackTrace();}
