Фрагменты должны вызывать регистр RegisterForActivityResult() перед их созданием. ⇐ Android

[Anonymous]

Я работаю над приложением для покупок и создал фрагмент для добавления продуктов в список продуктов.
Мне нужно прочитать разрешение внешнего хранилища, чтобы добавить фотографию к продуктам, поэтому я пытаюсь использовать RegisterForActivityResult() в своем фрагменте, но получаю ошибку.
Я новичок в программировании для Android, поэтому не знаю, правильно ли я его использую.
Я попробовал все ответы на другие вопросы, которые я задавал найдены, но они не работают.
Сообщение об ошибке:
IllegalStateException: Fragment AddActivity after being created. Fragments must call rHgS5orgPvsuzJ7shn8vw28y1XaePY4uDP() before they are created (i.e. initialization, onAttach(), or onCreate()).
