What's the best method for periodic tasks (a watcher thread)?

I need to execute periodic http requests. I use volley for the requests, but I don't want to overflow the queue.

Right now I've got a thread that enqueues the request and waits for 3 seconds.

AtomicBoolean quitUsersWatcher = new AtomicBoolean(false);

class UsersWatcher extends Thread {
    final Context context;
    ActiveUsersWatcher(Context c) {
        context = c;
    }
    public void run() {
        while (!quitUsersWatcher.get()) {
            JsonArrayRequest usersRequest = new JsonArrayRequest(Request.Method.GET, Config.ALL_USERS_URL, null,
                    this::getUsers,
                    Throwable::printStackTrace
            );

            try {
                RequestQueue queue = MySingleton.getInstance(context).getRequestQueue();
                queue.add(usersRequest);
                sleep(3000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }

    private void getUsers(JSONArray jsonResult) {
        //some logic
    }
}

But I don't this that sleep is the best idea. I thought about a variable that increases by 1 up to 64 or 128 and then enqueues the request. Like this:

int counter = 0;
while (!quitUsersWatcher.get()) {
    if(counter >= 128) {
        JsonArrayRequest usersRequest = new JsonArrayRequest(Request.Method.GET, 
        Config.ALL_USERS_URL, null, 
        this::getUsers, 
        Throwable::printStackTrace);

        RequestQueue queue = MySingleton.getInstance(context).getRequestQueue();
        queue.add(usersRequest);
        counter = 0;
    }

    ++counter;        
}

But maybe there are some better tools to do something like this. I tried to search for a watcher, but I couldn't find anything useful.

How would you implement something like this?

You can either use WorkManager or Alarm Manager for calling the api repeatedly. Check this documentation on how to handle background tasks in Android.
