Volley JsonObject Request (method get) not working

I am using volley for connecting to my rest web service. I have an .php address that return a json object. I use this code in my android app to get this object:

public void getData()
final ProgressDialog progressDialog = new ProgressDialog(this);
progressDialog.setMessage("Loading...");
progressDialog.show();

JsonObjectRequest jsonArrayRequest = new JsonObjectRequest(Request.Method.GET,URI_AZMOON_QUESTIONS,null,
new Response.Listener<JSONObject>()
@Override
public void onResponse(JSONObject response)
String s="t";

, new Response.ErrorListener()
@Override
public void onErrorResponse(VolleyError error)
Log.e("Volley", error.toString());
progressDialog.dismiss();

);
requestQueue.add(jsonArrayRequest);



but this request never runnig. I mean when I debug the program it never go to the onResponse and onErrorResponse methods.

onResponse

onErrorResponse

Update

this my Code:

import android.app.ProgressDialog;
import android.content.Context;
import android.net.ConnectivityManager;

try StringRequest intead of JsonArrayRequest (StringRequest always works for me)

StringRequest jsonArrayRequest = new JsonArrayRequest(Request.Method.GET, URI_AZMOON_QUESTIONS,
new Response.Listener<String>() @Override
public void onResponse(JSONArray response)


, new Response.ErrorListener()
@Override
public void onErrorResponse(VolleyError error)
Log.e("Volley", error.toString());
progressDialog.dismiss();

);
requestQueue.add(jsonArrayRequest);
}
