Étudier Kotlin pour le développement Android

Introduction

The book «Learn Kotlin for Android Development» (authors — Peter Späth and Leonardo Marcelino, 2019, 668 pages) is a fundamental guide that helps developers learn the Kotlin language and immediately apply it to create Android applications. Unlike many textbooks that either focus only on Kotlin syntax or immediately throw the reader into complex projects, this book offers a balanced path: from the basics of the language to professional Android development using modern libraries and tools.

The edition was published in 2019, when Kotlin had already become the official language for Android (Google announced this in 2017) but was not yet as widespread as it is today. Therefore, the book is especially valuable for those who want to understand why Kotlin is better than Java and how to make a smooth transition.

What the book is about

The book is divided into three logical parts that sequentially guide the reader from a beginner to a confident Android developer.

Part 1: Kotlin Basics

The first chapters are dedicated to the Kotlin language: variables, data types, functions, control structures, classes, objects, inheritance, interfaces, lambdas, coroutines. The authors do not just list the syntax but explain how each construct is applied in real Android development. Special attention is paid to null safety — one of the key features of Kotlin that eliminates millions of NullPointerException.
