Preface to Kotlin for Android Developers eBook
Hey! Thanks so much for your interest in this book, I’m really glad you decided to become a Kotlin for Android expert.
Many things have happened since I started writing “Kotlin for Android Developers” in mid-2015. At that point, Kotlin was still in an early access edition. But I felt so much power in the language, that I decided to explain all that I was learning in a book.
Since then, the language has kept growing to the point that Google announced that they would start supporting Kotlin as an official language to develop Android Apps.
This was amazing news. But it was even more amazing that both Google and Jetbrains suggested this book to Android developers that want to learn the language.
As you may know, this is a lean publication. This means that the book grew and progressed thanks to the reader’s comments. So I can only thank you for helping me bring this dream to life.
What is Kotlin for Android Developers about
In this book, I’ll be creating an Android app from the ground up using Kotlin as the main language. The idea is to learn the language by example, instead of following a regular reference book structure.
I’ll be stopping to explain the most interesting concepts and ideas about Kotlin, comparing them to Java 6. This way, you can see what the differences are and which parts of the language will help you speed up your work.
This book is not meant to be a language reference, but a tool for Android developers to learn Kotlin and be able to continue with their own projects by themselves.
I’ll be solving many of the most recurring problems we have to face in our daily lives as App developers, by making use of Kotlin expressiveness and some other really interesting tools and libraries.
However, this text covers most Kotlin features, so by the end of the reading, you will have deep knowledge about the language.
The content is very practical, so I recommend you to follow the examples and the code in front of a computer and try everything it’s suggested.
You could, however, take a first read to get a broad idea and then dive into practice. Even though this book now finished, I will review it from time to time to keep it up to date with new Kotlin versions.
So feel free to write and tell me what you think about the book, or what could be improved. I want this book to be the perfect tool for Android developers, and as such, help and ideas will be welcomed.
