Почему прослушиватель сетевых изменений не работает в моем приложении?

Я хочу архивировать прослушиватель изменений сети в своем приложении. Например: когда я запускаю свое приложение без мобильных данных и Wi-Fi, оно показывает «Сеть недоступна!». После этого, когда я ВКЛЮЧАЮ Wi-Fi или мобильные данные, он автоматически получает данные онлайн и показывает их в пользовательском интерфейсе.

У меня есть основная активность, которая уже расширяет интерфейс реализации фрагмента, а также базовый фрагмент. Я пробовал широковещательный приемник, но он не работает. когда я запускаю приложение без сети, оно дважды показывает отсутствие подключения к Интернету. И после включения Wi-Fi не обновляется автоматически, но когда я нажимаю «Другой вариант» в меню, отображается пользовательский интерфейс. Помогите пожалуйста мне...

1- Основная деятельность
