keep data in one class to pass to every activity

Question

i have a data that i got from json. and i need that data to every activity in my project. if i pass it using getExtra with intent when i back to other activity the data may lost. so i want to make a class that can keep the data so i can call it in every activity when i need it. is it possible? if yes how?

this is my example code when i call json. and maybe i think i want to make this call function to another class so i can call the data in every activity

try {
            OkHttpClient client = new OkHttpClient();

            Request request = new Request.Builder()
                    .url("https://example.com/user")
                    .get()
                    .addHeader("Accept", "application/json")
                    .addHeader("Authorization", "Bearer " + token)
                    .addHeader("Cache-Control", "no-cache")
                    .addHeader("Postman-Token", "e03845a5-dcb4-4835-9a9a-e9574fb5ed73")
                    .build();

            Response response = client.newCall(request).execute();
            Log.d("respon after token", "" + response);
            Log.d("json", "" + response.body().string());
            String jsonData = response.body().string();
            JSONObject object = new JSONObject(jsonData);
            token = object.getString("id");
            token = object.getString("name");
            token = object.getString("username");
            token = object.getString("email");
        } catch (IOException | JSONException e) {
            e.printStackTrace();
        }

You can use Shared Preference for storing and using the same data in different different activity :- see this link :- https://stackoverflow.com/a/23024962/2919483 — Rajshree Tiwari, Jul 27 '18 at 13:29
