To get the most out of this book

To succeed with this book, you don't need any experience whatsoever. If you are confident with your operating system of choice (Windows, Mac, or Linux), you can learn to make Android apps while learning the Kotlin programming language. Learning to develop professional quality apps is a journey that anybody can embark upon and stay on for as long as they want.

If you do have previous programming (Kotlin, Java, or any other language), Android, or other development experience, then you will make faster progress with the earlier chapters.
