Getting Started with KSOAP on Android
i am trying to create web service call in Visual Studio 2008. But while running android application i am not getting any output in emulator. can you please tell me whats the problems in my coding so that i can fix it.
_
Public Function HelloWorld() As String
Return "Hello how are you"
End Function
similarly in .java file of android i have used codings as:
package com.webservicetest;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import android.app.Activity;
public class webservicetest extends Activity {
private static final String NAMESPACE = "http://localhost/webservicetest/" ;
private static final String URL = "http://192.168.1.10/webservicetest/Service.asmx";
private static final String HelloWorld_SOAP_ACTION = "http://localhost/webservicetest/HelloWorld";
private static final String METHOD_NAME1 = "HelloWorld";
public static void main(String[] args)
{
Get开发者_JAVA技巧HelloWorld();
}
/** Called when the activity is first created. */
public static void GetHelloWorld() {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME1);
//SoapSerializationEnvelope envelope =new SoapSerializationEnvelope(SoapEnvelope.VER11);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try
{
androidHttpTransport.call(HelloWorld_SOAP_ACTION, envelope);
SoapObject response = (SoapObject)envelope.getResponse();
int result = Integer.parseInt(response.getProperty(0).toString());
}
catch(Exception e)
{
e.printStackTrace();
}
}
}
i am getting error in int result = Integer.parseInt(response.getProperty(0).toString());
as "The local variable result is never read".
The error you point out is not what makes your app not running, it only says that you're using a variable but never read it. In Android development you don't use main()
method, but mostly you override Activity.onCreate()
.
Here you find some tutorials.
(the GetHelloWorld()
method seems ok)
