Getting ready
I'll be using Android Studio 3 to write code. You can get started by adding anko-sqlite dependencies to your project and creating a database helper, like we did in the Using SQLite database in Kotlin recipe. You will need to read and implement the previous recipe to be able to follow this recipe.
