------ Solution - -------------------------------------------
used in the activity The following code gets the

  InputStream input = getResources().openRawResource(R.raw.application);
  		BufferedReader read = new BufferedReader(new InputStreamReader(input));
  		String line = "";
  		while ((line = read.readLine()) != null) {
  			if (line.contains("app.server")) {
  				String url = line.split("=")[1];
  System.out.println(url);
  				
  			}
  		}
