Of course it won't. Here comes the virtualization in picture.

Quote:
Android will not be able to communicate with Visual Studio's Development Server, hence you would be required to deploy your services at IIS and with help from your local system IP address, provide DNS to Android.

You android emulator is a different device (or rather I'd say, device running the android OS) that runs on the same machine, which already have OS running on it.
Let me give you one simple example to understand this, your machine would have any IP address, but this emulator-AVD also would have the IP address, which is not as same as you machine's.

So it won't access any of the resources from your machine. If you're running this URL http://localhost:33396/MainWEB.svc on emulator itself, it won't work but in your local machine's browsers.

If you might have noticed the URL in my answer, it consist of machine's IP address.

So host your WCF service on your local IIS, access this service from IIS. Then you'd get service URL replacing localhost with your machine IP and that is accepted by AVD. For example URL would be, http://192.175.21.15/MainWEB.svc/.

You can get a help for hosting the WCF on IIS from,

Hope you got the idea ! :)

this is my code with internet permission

protected String doInBackground(Void... params) {
// TODO Auto-generated method stub

DefaultHttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet("http://localhost:33396/FalconCPDataService.svc/DEChannelSettings");
// HttpGet request = new HttpGet("http://services.odata.org/OData/OData.svc/Products");

request.setHeader("Accept", "application/json");
request.setHeader("Content-type", "application/json");

try {
response = client.execute(request);

entity = response.getEntity();
if(entity.getContentLength() != 0)
{
reader = new InputStreamReader(entity.getContent(),"UTF-8");
String res=reader.toString();
char[] buffer = new char[(int) entity.getContentLength()];
reader.read(buffer);

try {
/*JSONObject object = new JSONObject(result);
JSONArray Jarray = object.getJSONArray("contacts");

for (int i = 0; i < Jarray.length(); i++) {
JSONObject Jasonobject = Jarray.getJSONObject(i);*/
Log.v("log_tag", "Error parsing data ");
jar = new JSONArray(new String(buffer));
for(int i=0; i<jar.length(); i++)
="" {
="" hashmap<string,="" string=""> item = new HashMap<string, string="">();
obj = jar.getJSONObject(i);
String City = obj.getString("ChannelID");
}
reader.close();

HttpGet request = new HttpGet("http://localhost:33396/FalconCPDataService.svc/DEChannelSettings");

How many times I have told you, specify IP here as well in place of localhost.
