Generating Java from WSDL for use on Android with ksoap2-android SOAP client?

I found this tool to auto generate wsdl to android code,

http://www.wsdl2code.com/example.aspx

Here is the code:

public void callWebService()    {
    SampleService srv1 = new SampleService();
    Request req = new Request();
    req.companyId = "1";
    req.userName = "userName";
    req.password = "pas";
    Response response =  srv1.ServiceSample(req);
}
