I am using Volley JsonObjectRequest and my model is parsed with Gson library. I have also implemented WCF webservice.

[WebInvoke(Method = "POST",
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json,
UriTemplate = "simplePostExample", BodyStyle = WebMessageBodyStyle.Bare)]

Test simplePostExample(Test test);

Test is custom object.

it is working perfectly in my scenario.

public class CustomJsonRequest extends JsonRequest<T> {

        private Class<T> mType;
        private String mEncodedCharSetProtocol = "utf-8";

        CustomJsonRequest(int method, String url, Class<T> type, JSONObject jsonRequest,
                      Response.Listener<T> listener, Response.ErrorListener errorListener) {
            super(method, url, (jsonRequest == null) ? null : jsonRequest.toString(), listener,
                    errorListener);
            this.mType = type;
        }


        @Override
        protected Response<T> parseNetworkResponse(NetworkResponse response) {
            try {
                String parsed;
                try {
                    if (mEncodedCharSetProtocol != null) {
                        parsed = new String(response.data, mEncodedCharSetProtocol);
                    } else {
                        parsed = new String(response.data,
                                HttpHeaderParser.parseCharset(response.headers));
                    }
                } catch (UnsupportedEncodingException e) {
                    parsed = new String(response.data);
                }
                Gson gson = new Gson();
                return Response.success(gson.fromJson(parsed, mType),HttpHeaderParser.parseCacheHeaders(response));
            } catch (Throwable e) {
                return Response.error(new ParseError(e));
            }
        }
    }

Also include Gson library

implementation 'com.google.code.gson:gson:2.8.2'

I hope it will work.
