Iam trying to connect my App to a WCF service that I created in asp.net. The service runs on my localmachine: http://localhost:8080/Service.svc/

But for some reasons my Android can not connect to this http-adress.

This is the error:

09-12 14:50:44.540: WARN/System.err(593): org.apache.http.conn.HttpHostConnectException: Connection to http://127.0.0.1:8080 refused
this is the method in wcf, Iam trying to return a collection with some values.

        /// <returns>An enumeration of the (id, item) pairs. Returns null if no items are present</returns>
    protected override IEnumerable<KeyValuePair<string, SampleItem>> OnGetItems()
    {
        // TODO: Change the sample implementation here
        if (items.Count == 0)
        {
            items.Add("A", new SampleItem() { Value = "A" });
            items.Add("B", new SampleItem() { Value = "B" });
            items.Add("C", new SampleItem() { Value = "C" });
        }
        return this.items;
    }


And this is how the connection in the android looks like:

public void getData(String url)
{
    HttpClient httpClient = new DefaultHttpClient();
    HttpGet httpGet = new HttpGet(url);
    HttpResponse response;

    try
    {
        response = httpClient.execute(httpGet);
        Log.i(TAG,response.getStatusLine().toString());
} catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }/* catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } */catch (Exception e){
        e.printStackTrace();
    }finally{
        httpGet.abort();
    }
}
A: 

127.0.0.1 refers to localhost in the Emulator, not your machine.

Use 10.0.2.2 to connect to your host machine.

Do also make sure you have requested the INTERNET permission in your AndroidManifest.xml

thanks it worked,
Troj
do you know how it's possible to read the data that was sent?
Troj
You can use WireShark on the host machine for exactly this purpose.
