Question

I am using ArchitectureComponents in my application.I am making API request from ViewModel and setting data to RecyclerView using ViewModel in ActivityMain.For making a Api call I need a Token which is saved in SharedPreference.I need to get that token and add it in Headers while making request.Where and how to get the SharedPreference value. It should be get in ViewModel or Repository.
This is code for my ViewModel

public class FoodieViewModel extends AndroidViewModel {
   FoodieRepository repository;
   MutableLiveData<ArrayList<Foodie>> foodieList;
    public FoodieViewModel(@NonNull Application application) {
        super(application);
        repository=new FoodieRepository(application);
    }

     LiveData<ArrayList<Foodie>> getAllFoodie(){
        if(foodieList==null){
            foodieList=new MutableLiveData<ArrayList<Foodie>>();
            loadFoodies();
        }
        return foodieList;
    }
    public void loadFoodies(){
        String url="somethimg.com";
        JsonArrayRequest request =new JsonArrayRequest(Request.Method.GET, url, null, new Response.Listener<JSONArray>() {
            @Override
            public void onResponse(JSONArray response) {
                ArrayList<Foodie> list=new ArrayList<>();
                try {
                    for(int i=0;i<response.length();i++){
                        JSONObject obj=response.getJSONObject(i);
                        Foodie foodie=new Foodie();
                        String name=obj.getString("firstname");
                        foodie.setName(name);
                        list.add(foodie);
                    }

                }catch (JSONException e){
                    e.printStackTrace();
                }
                foodieList.setValue(list);

            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {

            }
        }){
            @Override
            public Map<String, String> getHeaders() throws AuthFailureError {
                Map<String, String> headers = new HashMap<>();
                String auth = "JWT " + "sometoken";
                headers.put("Authorization", auth);
                headers.put("Content-Type", "application/json");
                return headers;
            }

        };
        AppController.getInstance().addToRequestQueue(request);
    }
