GSON sends my object as a string not a object

I am using Volley with GSON and I need to send a object as a parameter to my call.

This is how I do the object:

JSONObject params = new JSONObject();
        Gson gson = new Gson();
        String json = gson.toJson(route);
params.put("route", json);

And then I call my Volley JsonObjectRequest function.

The problem is that the params look like this:

{"route":"{\"bounds\":{\"northeast\":{\"lat\":52.3777194,\"lng\":4.924666999999999},\"southwest\":{\"lat\":52.36881109999999,\"lng\":4.9011479}},\"copyrights\":\"Map data ©2014 Google\", etc...}"

As you can see, instead of sending it as a object, its sending it as a String , and that's why I get the " before the {} (before the object begins). The params should look like:

   {"route":{\"bounds\":{\"northeast\":{\"lat\":52.3777194,\"lng\":4.924666999999999},\"southwest\":{\"lat\":52.36881109999999,\"lng\":4.9011479}},\"copyrights\":\"Map data ©2014 Google\", etc...}

So no " before { like this: 

{"route":{myObject}

What an I doing wrong here?

You don't want to mix JSONObject and GSON. That's 2 different libraries.

Use gson.toJsonTree to obtain an element, then use JsonObject instead of JSONObject:

JsonObject params = new JsonObject();
Gson gson = new Gson();
params.add("route", gson.toJsonTree(route));
