This is the JSON that my API return:

{
    "success": true,
    "message": "User successfully retrieved",
    "data": {
        "id": "1",
        "username": "admin",
        "password": null,
        "created": "2018-04-15 11:53:28",
        "modified": "2018-04-15 11:53:28",
        "grade": "4",
        "gradename": "Administrator",
        "department": "5",
        "departmentname": "Operations"
    }
}

The data part is what i need to parse. I beleive that the data part is another json object. How can I access it from Android?


This is the code I have used in the past:

            managerSecurityApi.login (etUsername.getText ().toString (), etPassword.getText ().toString (), new Callback<ArrayList<ObjectUser>>() {
                @Override
                public void onResponse (@NonNull Call<ArrayList<ObjectUser>> call, @NonNull Response<ArrayList<ObjectUser>> response) {
                    ArrayList<ObjectUser> JSONList = response.body();
                    for (int i = 0; i < Objects.requireNonNull(JSONList).size(); i++) {
                        objectUser.add(new ObjectUser (
                                JSONList.get(i).getId(),
                                JSONList.get(i).getUsername(),
                                JSONList.get(i).getGrade(),
                                JSONList.get(i).getGradename(),
                                JSONList.get(i).getDepartment(),
                                JSONList.get(i).getDepartmentname()
                        ));

But the information I need to access is in the data object in the JSON response. I am not sure how to access it.
