Solution 1:

For anyone else coming across this, you need to forget about the header override and setup your own getBodyContentType() and getBody() methods. Follow this pattern:

StringRequest stringRequest = new StringRequest(Request.Method.POST, url, successListener, errorListener) {
        @Override
        public String getBodyContentType() {
            return "application/json; charset=utf-8";//set here instead
        }

        @Override
        public byte[] getBody() {
            try {
                Map<String, String> params = yourObject.getMappedParams();
                JSONObject json = new JSONObject(params);
                String requestBody = json.toString();
                return requestBody == null ? null : requestBody.getBytes("utf-8");
            } catch (UnsupportedEncodingException uee) {
                return null;
            }
        }
    };
