Kotlin and Android Development featuring Jetpack

Add the Navigation Drawer

We likely won’t need any additional dependencies here for the nav drawer since we added the androidx.navigation library last chapter and apps now by default include the Material Design Components library. If either are missing, though, add them now. We can then jump over to activity_main.xml to add in the nav drawer.

<androidx.drawerlayout.widget.DrawerLayout
