1) Add Dependencies
Add Facebook Ads and Recyclerview Dependencies in app level build.gradle
//Recyclerview
implementation "androidx.recyclerview:recyclerview:1.1.0"
//Ads
implementation "com.facebook.android:audience-network-sdk:5.8.0"2) Add recyclerview to UI
Add recyclerview layout to your activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
