Answer 1

Following three steps should make it work for old Volley libraries lacking this suport.

1. Prepare payload and post:

                       JSONArray payloadItems = new JSONArray();
   
                 JSONObject payloadItem1=new JSONObject();
                //set properties on item1
                payloadItem1.put('prop1',"val11");
   
                 payloadItems.put(payloadItem1);
   
                JSONObject payloadItem2=new JSONObject();
                //set properties on item1
                payloadItem2.put('prop1',"val12");
   
                payloadItems.put(payloadItem1);
   
   
                JsonArrayRequest request;
   
                request = new JsonArrayRequest(Request.Method.POST,url,payloadItems, new Response.Listener() {
                   @SuppressWarnings("unchecked")
                   @Override
                   public void onResponse(JSONArray response) {
                       //your logic to handle response
                   }
               }, new Response.ErrorListener() {
                   @Override
                   public void onErrorResponse(VolleyError error) {
                       //your logic to handle error
                   }
               }) {
   
                   public Map getHeaders() throws AuthFailureError {
                       Map params = new HashMap();
                       /* This is very important to pass along */
                       params.put("Content-Type","application/json");
                       //other headers if any
                       return params;
                   }
   
                    };
   
   
   
   
                   request.setRetryPolicy(new DefaultRetryPolicy(10000, 2, 2));
                   VolleyHelper.init(this);
                   VolleyHelper.getRequestQueue().add(request);
   

2. [If Needed] Add this constructor in Class- JsonArrayRequest in Volley package if not already there

     public JsonArrayRequest(int method, String url, JSONArray jsonArray, Listener listener, ErrorListener errorListener) {
       super(method, url, (jsonArray == null) ? null : jsonArray.toString(),
               listener, errorListener);
   

   }

3. [If Needed] Override this method if not yet implemented to support JSONArray response from server.

    @Override
    protected Response parseNetworkResponse(NetworkResponse response) {
        String responseString;
        JSONArray array = new JSONArray();
        if (response != null) {
   
            try {
                responseString = new String(response.data, HttpHeaderParser.parseCharset(response.headers));
                JSONObject obj = new JSONObject(responseString);
                (array).put(obj);
            } catch (Exception ex) {
            }
        }
        //return array;
        return Response.success(array, HttpHeaderParser.parseCacheHeaders(response));
    }
