Hello Paul,
On Android, Kotlin is calling the underlying component framework, so it works in a very similar way to Java code. However you will find that although it is using all the same RecyclerView code etc. in the same way, it will be a little more concise. In other areas of Android development, such as multi-tasking, Kotlin co-routines will be a much more efficient way of thinking about designing the code.
We should point out that Head First Kotlin is really a language book, so we don't really go into the specifics of Kotlin coding on Android. For that, you might want to look at future versions of our companion book, Head First Android...
Thanks for the question :-)
