iam trying to make facebook Scrap my url automatically when i share it
instead of making it manually by this page

https://developers.facebook.com/tools/debug/og/object/

and i used volley to achieve it

but it didnt work and give me an error

so the code is

String fbLink = "https://graph.facebook.com/";

    StringRequest postRequest = new StringRequest(Request.Method.POST, fbLink,

            new Response.Listener<String>()

            {

                @Override

                public void onResponse(String response) {

                    // response

                    Log.d("Response", response);

                }

            },

            new Response.ErrorListener()

            {

                @Override

                public void onErrorResponse(VolleyError error) {

                    // error

                    Log.d("Error.Response", error.toString());

                }

            }

    ) {

        @Override

        protected Map<String, String> getParams()

        {

            Map<String, String> params = new HashMap<String, String>();

            params.put("id", Link);

            params.put("scrape", "true");

            params.put("access_token", "53423443434234534");



            return params;

        }

    };

    queue.add(postRequest);
