Question

У меня есть AppCompatActivity и PreferenceFragment, но в onCreate из AppCompatActivity PreferenceFragment не завышена. Код и ошибка:

Я не знаю, нужно ли мне импортировать что-то другое или получить другую библиотеку или использовать PreferenceFragmentCompat, но я думаю, что это то же самое.
