      OAuthRequest request = new OAuthRequest(Verb.GET, PROTECTED_RESOURCE_URL);
      request.addBodyParameter("track", "prova");
      Token requestToken = new Token(MYACCESSTOKEN,MYACCESSTOKENSECRET);
  
      service.signRequest(requestToken, request);
      Response response = request.send();
      System.out.println(response.getBody());
      }
