Use sectionedrecyclerviewadapter But compiler Error

Question

I have to use recycler section in my project, but when I add the tool below:

SectionedRecyclerViewAdapter

when I add gradle

implementation 'io.github.luizgrp.sectionedrecyclerviewadapter:sectionedrecyclerviewadapter:1.2.0'

then, the NotificationCompact

import android.support.v7.app.NotificationCompat;

Can't be found! How should I do to use recycler section?
