Метод интерфейса для намерения не работает во фрагменте

Question

У меня проблема. Я хочу использовать метод onNewIntent() во фрагменте. К счастью, я получил один действительно хороший ответ ( Пожалуйста, посмотрите ). Я пытался работать с этим фрагментом кода, но, к сожалению, тег NF C не читается. Что я делаю не так? Надеюсь, вы поможете мне с этим вопросом. Буду очень благодарен за каждый ответ. Новый код всегда вставлялся между строками комментариев // NEW INTENT
