In general for setting a custom header you need to override getHeaders and set the custom header manually. However, volley handles content type headers differently and getHeaders way does not always work.

So for your case you need to override getBodyContentType. So your code will look like

JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(url, jsonBody,new Response.Listener() {

@Override
public void onResponse(JSONObject response) {
   Log.d("TAG", response.toString());
}, new Response.ErrorListener(){
        @Override
        public void onErrorResponse(VolleyError error) {
            Log.e("TAG", error.getMessage(), error);
        }


    }){
         @Override
         public String getBodyContentType(){
              return "application/json";
         }
    };
