web service in android/eclipse

Question

I need to consume a web service from android/eclipse by soap method.

ie., i have to give an input and show an appropriate result from the web service as per the users input.How to do this?

java class

public class Demo_webserviceActivity extends Activity
{ 
/** Called when the activity is first created. */

   private static String NAMESPACE = "http://tempuri.org/";
   private static String METHOD_NAME = "GetName";
    private static String SOAP_ACTION = "http://tempuri.org/GetName";
    private static String URL = "http://122.248.240.105:234/Service1.asmx";

   Button btnFar;
   EditText txtFar,txtCel;


   @Override
   public void onCreate(Bundle savedInstanceState)
   {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.main);

   btnFar = (Button)findViewById(R.id.btnFar);

   txtFar = (EditText)findViewById(R.id.txtFar);
   txtCel = (EditText)findViewById(R.id.txtCel);

   btnFar.setOnClickListener(new View.OnClickListener()
   {

   public void onClick(View v)
   {
     //Initialize soap request + add parameters
     SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);       

     //Use this to add parameters
     request.addProperty("Fahrenheit",txtFar.getText().toString());

     //Declare the version of the SOAP request
     SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

     envelope.setOutputSoapObject(request);
     envelope.dotNet = true;

     try 
     {
         HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

         //this is the actual part that will call the webservice
         androidHttpTransport.call(SOAP_ACTION, envelope);

         // Get the SoapResult from the envelope body.
         SoapObject result = (SoapObject)envelope.bodyIn;

         if(result != null)
         {
          //Get the first property and change the label text
           txtCel.setText(result.getProperty(0).toString());
         }
         else
         {
           Toast.makeText(getApplicationContext(), "No Response",Toast.LENGTH_SHORT).show();
         }
    }
    catch (Exception e)
    {
       e.printStackTrace();
       }
     }
       });
    } 
 }

web method

public class GetName 
{
public String GetName(String Fahrenheit){
    return(Fahrenheit);
}
}

Thanks a lot

Answer 1

You should use SoapPrimitive results = (SoapPrimitive)envelope.getResponse(); instead of SoapObject result = (SoapObject)envelope.bodyIn; because your webservice is returning a string not object .

Answer 2

You are going in right direction ie The code you are written in android is right.Just make sure that soap action , Method , URl and namespace you are written is right. If you have any doubts regarding this or any other doubts you can write me.
