Ошибка в Glide (class file for android.support.v4.app.Fragment not found)

Хочу создать галерею, сделал отдельный проект, на активити, все работает, с фрагментами у меня беда. Ругается на Glide при запуске проекта. https://code.tutsplus.com/ru/tutorials/code-an-image-gallery-android-app-with-glide--cms-28207 - делал по этому туториолу.
