Consuming WCF Service with Android

I have the following code in a WCF Service that returns a string, and I’m trying to consume it in an Android app.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;

namespace HelloService
{
    public class HelloService : IHelloService
    {
        public string SayHello()
        {
            return "Bonjuor Android from WCF Service";
        }
    }
}

I have two problems,

1, I have no idea if I’m even close with the Java due to the try catch blocks. If I have them in the code the app works but doesn’t display the text in the toast or text view, and if I leave the try catch blocks out Eclipse tell me to fix the problem, add a try catch block…lol.

And 2, I have no idea what I’m doing.

@Override
public void onCreate(Bundle icicle)
{
    super.onCreate(icicle);
    setContentView(R.layout.contacts);               

try 
{

        DefaultHttpClient httpClient = new DefaultHttpClient();
        URI uri = new URI("http://www.themorningtonpeninsula.com/HelloService/HelloService.svc"); 

        HttpGet httpget = new HttpGet(uri + "/SayHello");
        httpget.setHeader("Accept", "application/json");
        httpget.setHeader("Content-type", "application/json; charset=utf-8");

        HttpResponse response = httpClient.execute(httpget);
        HttpEntity responseEntity = response.getEntity();

        long intCount = responseEntity.getContentLength();

        char[] buffer = new char[(int)intCount];
        InputStream stream = responseEntity.getContent();
        InputStreamReader reader = new InputStreamReader(stream, "UTF-8");
        try
        {
                reader.read(buffer);
                String str = new String(buffer);
                TextView thetext = new TextView(this);
                thetext.setText(str);
                setContentView(thetext);
                Toast.makeText(this, str, Toast.LENGTH_SHORT).show();
            }

            catch (IOException e) 
            {
                e.printStackTrace();
            }
            stream.close();

        }
        catch (Exception e) 
        {
            e.printStackTrace();
        }
    } 
}

Can someone please have a look at the code and let me know if I’m even close, or even better point me too, or post some code that does work???

I think you should use another Thread to do Networking task and also you can use runOnUiThread() method in order to do the UI updation like displaying your Toast, etc.

All fixed, the Java code works fine, the problem was my WCF Service needed work. It wasn’t passing back correctly formatted JSON objects. So I went back and and found a great tutorial simple and to the point. I must have completed 10 tutorials before finding this one. Pat on the back for the author.

Cheers,
