As you do not send a HttpRequest, you don't need these parameters. You should rather request content from Servlet via URLConnection and then read the data in your activity.

Example here: https://docs.oracle.com/javase/tutorial/networking/urls/readingWriting.html

Edit: I've read that you can use HttpGet in Activity like this:

DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
httpGet.addHeader("key", VALUE);
HttpResponse httpResponse = httpClient.execute(httpGet);
