I use this code to get response from webservice and it works fine

try {
                HttpPost request = new HttpPost(
                        "webservice url");
                request.setHeader("Accept", "application/json");
                request.setHeader("Content-type", "application/json");
                // Build JSON string
                JSONStringer loginuser = new JSONStringer().object().key("userid")
                        .value(SetGetValues.getUserid()).endObject();
                StringEntity entity = new StringEntity(loginuser.toString());
                request.setEntity(entity);
                Log.v("data", loginuser.toString());
                // Send request to WCF service
                DefaultHttpClient httpClient1 = new DefaultHttpClient();
                HttpResponse response = httpClient1.execute(request);
                Log.v("response code", response.getStatusLine().getStatusCode()
                        + "");
                HttpEntity responseEntity = response.getEntity();
                // Read response data into buffer
                char[] buffer = new char[(int) responseEntity.getContentLength()];
                InputStream stream = responseEntity.getContent();
                InputStreamReader reader = new InputStreamReader(stream);
                reader.read(buffer);
                stream.close();
                results = new JSONArray(new String(buffer));
    }catch(Exception e){
    // TODO: handle exception
                e.printStackTrace();
}

check out the following line

Log.v("response code", response.getStatusLine().getStatusCode()
                            + "");

if its value is 200 then you r getting ok response from server else you are not getting response from server
