First of all, thank you for this simple tutorial. That was exactly what i needed, because I'm quite unexperienced with Android and Java.

But now I have a question on how to take it a step further. How can I read custom classes? For example if i had this webmethod:

Syntax: [ Download ] [ Hide ]
Using java Syntax Highlighting
  1.  
  2. namespace WebService1
  3.  
  4. {
  5.  
  6.  
  7.  
  8.     [WebService(Namespace = "http://tempuri.org/")]
  9.  
  10.     [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
  11.  
  12.     [ToolboxItem(false)]  
  13.  
  14.  
  15.  
  16.     public class Service1 : System.Web.Services.WebService
  17.  
  18.     {
  19.  
  20.  
  21.  
  22.         [WebMethod]
  23.  
  24.         public HelloWorldResult HelloWorld()
  25.  
  26.         {
  27.  
  28.             return new HelloWorldResult();
  29.  
  30.         }
  31.  
  32.  
  33.  
  34.         public class HelloWorldResult
  35.  
  36.         {
  37.  
  38.            string a = "Hello";
  39.  
  40.            string b = "World";
  41.  
  42.         }
  43.  
  44.     }
  45.  
  46. }
  47.  
  48.  
Parsed in 0.035 seconds, using GeSHi 1.0.8.4


As Result i get something like {HelloWorldResult=anyType{};}.

And something else to your code: when i run it, I only get a result every second time I press the button. The other times I get this error: "unexpected type (position:END_DOCUMENT null@1:0 in java.io.InputStreamReader@43618678)"
Any Idea why? Or do you know this behaviour?

Thanks a lot in advance!

Hi,
How can I fix this bug (androidHttpTransport.call(SOAP_ACTION, envelope); causes an exception)

My Java code is the following:


Syntax: [ Download ] [ Hide ]
Using java Syntax Highlighting
  1.  private static final String SOAP_ACTION = "http://tempuri.org/HelloWorld";
  2.  
  3.    private static final String METHOD_NAME = "HelloWorld";
  4.  
  5.    private static final String NAMESPACE = "http://tempuri.org/";
  6.  
  7.    private static final String URL = "http://127.0.0.1:1483/WebSite2/Service.asmx";
  8.  
  9.  
  10.  
  11.    @Override
  12.  
  13.    public void onCreate(Bundle savedInstanceState) {
  14.  
  15.       super.onCreate(savedInstanceState);
  16.  
  17.       setContentView(R.layout.main);
  18.  
  19.  
  20.  
  21.       mResult = (EditText) findViewById(R.id.result);
  22.  
  23.       try {
  24.  
  25.          SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
  26.  
  27.  
  28.  
  29.          SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
  30.  
  31.          envelope.dotNet = true;
  32.  
  33.          envelope.setOutputSoapObject(request);
  34.  
  35.          AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(URL);
  36.  
  37.          try {
  38.  
  39.             <span style="font-weight: bold">androidHttpTransport.call(SOAP_ACTION, envelope);</span> //Throw exception here!!!
  40.  
  41.             SoapObject resultsRequestSOAP = (SoapObject) envelope.bodyIn;
  42.  
  43.             mResult.setText("Ganzes Rückagbeobjekt:\n");// +resultsRequestSOAP.toString());
  44.  
  45.          }
  46.  
  47.  
  48.  
  49.          catch (Exception e) {
  50.  
  51.             mResult.setText("NG1\n");
  52.  
  53.          }
  54.  
  55.  
  56.  
  57.       } catch (Exception e) {
  58.  
  59.          mResult.setText("NG2\n");
  60.  
  61.       } finally {
  62.  
  63.          mResult.setText("NG3\n");
  64.  
  65.       }
  66.  
  67.    }
Parsed in 0.040 seconds, using GeSHi 1.0.8.4



The C# code is as follow:

using System.Web.Services.Protocols;
using System.Xml.Linq;

[WebService(Namespace = "http://tempuri.org/")]

{
    public Service () {
    }

    [WebMethod]
    public string HelloWorld() {
        return "Hello World";
