Android Volley JsonRequest receiving the wrong return

Question

After make a request the volley listener called is onErrorResponse and for my surprise the error message is the callback that I wanted from my server, a json with correct datas.

What is strange thats a parseError but how's a parse error if I make the parse in the onResponse listener.

I'm new in android.

My method:

public void getAllEstablishmentsRequest(){

    String url = "http://myServer.com/something";

    RequestQueue requestQueue = Volley.newRequestQueue(this);

    JsonArrayRequest request = new JsonArrayRequest(url,
            new Response.Listener<JSONArray>(){
                @Override
                public void onResponse(JSONArray response) {
                    try {

                        JSONObject object = new JSONObject(response.toString());
                        JSONArray Jarray = object.getJSONArray("data");

                        for (int i = 0; i < Jarray.length(); i++) {
                            JSONObject Jasonobject = Jarray.getJSONObject(i);
                        }

                    } catch (JSONException e){
                        Log.e("Volley", "Error JSON");
                    }
                }
            },
            new Response.ErrorListener(){
                @Override
                public void onErrorResponse(VolleyError error){
                    Log.e("Volley", "Error - requisição das campanhas de Eutrofização");
                    System.out.println(error);
                }
            }
    );
    requestQueue.add(request);
}

Error: com.android.volley.ParseError: org.json.JSONException: Value {"data":{"establishments":[{"created_by":1,"phone":"(85) 3246-3834","teste":1453583589,"neighborhood":"Joaquim Távora","last_promotion":"2015-10-06 12:42:01","days_last_promotion":110,"id":2,"distance":0,"updated_at":"2015-10-06 12:42:01","address":"Av.

You are using JsonArrayRequest when you are getting a JsonObject as a response from the server. Use JsonObjectRequest instead. Something like this:

public void getAllEstablishmentsRequest(){

   String url = "http://myServer.com/something";

    RequestQueue requestQueue = Volley.newRequestQueue(this);

    JsonObjectRequest request = new JsonObjectRequest(url,
            new Response.Listener<JSONObject>(){
                @Override
                public void onResponse(JSONObject object) {
                    try {
                        JSONArray Jarray = object.getJSONArray("data");

                        for (int i = 0; i < Jarray.length(); i++) {
                            JSONObject Jasonobject = Jarray.getJSONObject(i);
                        }

                    } catch (JSONException e){
                        Log.e("Volley", "Error JSON");
                    }
                }
            },
            new Response.ErrorListener(){
                @Override
                public void onErrorResponse(VolleyError error){
                    Log.e("Volley", "Error - requisição das campanhas de Eutrofização");
                    System.out.println(error);
                }
            }
    );
    requestQueue.add(request);
}
