Start building native Android apps the modern way in Kotlin with Jetpack's expansive set of tools, libraries, and best practices. Learn how to create efficient, resilient views with Fragments and share data between the views with ViewModels. Use Room to persist valuable data quickly, and avoid NullPointerExceptions and Java's verbose expressions with Kotlin. You can even handle asynchronous web service calls elegantly with Kotlin coroutines. Achieve all of this and much more while building two full-featured apps, following detailed, step-by-step instructions.With Kotlin and Jetpack, Android development is now smoother and more enjoyable than ever before. Dive right in by developing two complete Android apps. With the first app, Penny Drop, you create a full game complete with random die rolls, customizable rules, and AI opponents. Build lightweight Fragment views with data binding, quickly and safely update data with ViewModel classes, and handle all app navigation in a single location. Use Kotlin with Android-specific Kotlin extensions to efficiently write null-safe code without all the normal boilerplate required for pre-Jetpack + Kotlin apps. Persist and retrieve data as full objects with the Room library, then display that data with ViewModels and list records in a RecyclerView. Next, you create the official app for the Android Baseball League. It's a fake league but a real app, where you use what you learn in Penny Drop and build up from there. Navigate all over the app via a Navigation Drawer, including specific locations via Android App Links. Handle asynchronous and web service calls with Kotlin Coroutines, display that data smoothly with the Paging library, and send notifications to a user's phone from your app. Come build Android apps the modern way with Kotlin and Jetpack! What You Need: You'll need the Android SDK, a text editor, and either a real Android device or emulator for testing. While not strictly required, it's assumed you're using Android Studio, which comes with the Android SDK and simplifies creating an emulator. Also, a few examples require JDK 1.8 or later, though all of these pieces can be completed in other ways when using JDK 1.6.

It is also a multiplatform language that can be used to write code that can be shared across platforms including macOS, iOS, Windows, and JavaScript. Based on Big Nerd Ranch’s popular Kotlin Essentials course, this guide shows you how to work effectively with Kotlin through hands-on examples and clear explanations of key Kotlin concepts and foundational APIs. Written for Kotlin 1.5, this book will also introduce you to JetBrains’ IntelliJ IDEA development environment. Whether you are an experienced developer or are learning your first programming language – and whether you are interested in Kotlin for Android, server-side, or multiplatform projects – the authors will guide you from first principles to advanced Kotlin usage. By the end of this book, you will be empowered to create reliable, concise applications in Kotlin.

Unleash the Power of Kotlin for Android App Development DESCRIPTION This book aims to provide the knowledge around the fundamental concept of Kotlin languages, and itÕs an application in Android application development. It covers basic to advanced concepts with practical examples. Each chapter in this book is a step by step journey towards the learning Kotlin and excel in various topics and concepts. It covers topics like data types, various functions, including lambdas and higher-order functions. It also covers advanced topics like Generics, Collections, DSL, Coroutine, etc. Most importantly, such concepts are explained with practical usage of it in Android application. You will get to know what is the best possible way to use these concepts while you develop an Android application. In this book, along with Kotlin, an attempt has been made where few Android-specific topics are also explained. For example, the application is using Architecture components, including ViewModel, LiveData, NavigationComponent, and also it uses Flow, which is a hot topic in Kotlin. While we learn this concept, along with that, we also develop a sample application where we can apply our learning and, in the end, have some tangible and measurable output. Readers with little previous knowledge of Android application development can easily follow this book. Most of the chapters are code-heavy and focuses on practical usage of KotlinÕs features. Each chapter has code on the GitHub. You can check out this code and try it out. Or you can develop in parallel and cherry-pick things from the sample code base as and when you need it. Few chapters also follow the quiz at the end, and you can self assess yourself by going through that quiz. In total there are ten chapters. KEY FEATURESÊÊ - The book has theories explained elaborately along with Kotlin code and corresponding output to support the theoretical explanations. The Kotlin codes are provided with step-by-step comments to explain each instruction of the code. - The book is quite well balanced with programs and illustrative real-case problems.Ê - The book is not just explaining theoretical concepts of the language. Still, it explains how the full-fledged application can be developed using some latest tools and technologies and create an excellent Android application using Kotlin. - Few of the chapter offers the quiz at the end of it. And you can revise the concepts quickly. - A rich sample application is created to demonstrate KotlinÕs capability in various parts of the application. - Quite the latest concepts are discussed in depth. For example, Flow, NavigationComponent, Coroutine, ViewModel, and LiveData. WHAT WILL YOU LEARNÊ - Know the basics and many advanced concepts of Android. - Able to code in Kotlin for your Android application. - You will know how architecture components can be used in Android application with Kotlin. - Writing tests that use coroutine, Flow, LiveData, and ViewModel. - What measures you need to take before you put an application in production. - How agile practices can be applied before and after the application development is started.
