Answer 1

You have make JSONObject Request Instead Of JsonArray Request.

  JsonObjectRequest req = new JsonObjectRequest (urlJsonArry,
                new Response.Listener<JSONObject>() 

Answer 2

The problem is that you are making a JSONArray Request,instead of an JsonObjectRequest that should be the correct implementation.

Also I recommend you to use Gson to parse Json, makes it easier to parse.
