A helper class to Google volley. Made with inspiration from AFNetworking. Usage:

    volley = new VolleyHelper(this,
            "<BASEURL>"/*Maybe get url from getString*/);

    
    volley.post("<service_name>", null,
            new Listener<JSONObject>() {

                @Override
                public void onResponse(JSONObject response) {

                    Log.i("Got JSON", response.toString());
                    
                }
            }, new ErrorListener() {

                @Override
                public void onErrorResponse(VolleyError error) {
                    Log.e("Volley Error", "Error getting JSON", error);

                }
            });
