i only get the OK response Response , and not the JSON, this my Code:
ApiClient GoProApi = ApiBase.getMediaClient().create(ApiClient.class); retrofit2.Call GetPhotos = GoProApi.getMediaList();

    GetPhotos.enqueue(new retrofit2.Callback<GoProMediaList>()
    {
        @Override
        public void onResponse(retrofit2.Call<GoProMediaList> call, retrofit2.Response<GoProMediaList> response) {

        }

        @Override
        public void onFailure(retrofit2.Call<GoProMediaList> call, Throwable t) {

        }
    });
