com.android.volley.ParseError: org.json.JSONException

If you want to receive the result as a string don't use the JSONRequest. Go with the simple Request class. Your problem is pretty simple the server is giving back a JSONArray with just one element inside. A JSONArray is not a JSONObject. That's why the parsing is failing.

We Have to use JsonArrayRequest instead of JsonObjectRequest. The code as:

    RequestQueue queue = Volley.newRequestQueue(this);

    final String url = "http://192.168.88.253/mybazar/get_product_list.php";

    // prepare the Request
    JsonArrayRequest getRequest = new JsonArrayRequest(Request.Method.GET, url, null,
            new Response.Listener<JSONArray>()
            {
                @Override
                public void onResponse(JSONArray response) {
                    // display response
                    Log.d("Response", response.toString());
                }
            },
            new Response.ErrorListener()
            {
                @Override
                public void onErrorResponse(VolleyError error) {
                    Log.d("Error.Response", error.toString());
                }
            }
    );



    // add it to the RequestQueue
    queue.add(getRequest);

Hope, it's solve the problem.

I noticed that there is class JsonArrayRequest supported by volley so I use this class and the problem solved, I was using JsonObjectRequest
