Learn Kotlin for Android Development - Peter Späth

2019
english

The book is for beginning software developers with little or no knowledge of programming, and for developers with knowledge of other languages who are interested in using Kotlin for future Android projects. The target platforms are Android devices. The book is not meant to present a thorough introduction into Android; instead, it uses Android as a platform as is and thoroughly introduces the Kotlin programming language and how it gets used for Android. Basic knowledge of how to use a desktop or laptop computer, including the installation and starting of programs, is expected. The operating system you want to use plays no major role, but because we are using Android Studio as a development environment, you must choose an operating system able to run this integrated development environment (IDE). This is the case for Linux, Windows, and Mac OS. Screenshots are taken from an Ubuntu Linux installation. In the end, you will be able to write and run Kotlin programs for Android of beginning to midlevel complexity.

От Java к Kotlin - Дункан Макгрегор, Нэт Прайс

2023
русский

 Книга описывает практические приемы рефакторинга и переноса кода написанных на Java мобильных приложений для Android  на язык Kotlin с сохранением совместимости. Приведено подробное сравнение этих двух языков, даны примеры перевода проектов с Java на Kotlin, добавления поддержки Kotlin в сборку Java.

 Показан переход от классов Java к классам Kotlin, от коллекций Java к коллекциям Kotlin, от объектов JavaBeans к значениям, от статических методов к функциям верхнего уровня. Подробно рассматривается обработка ошибок, приведены практические приемы управления проектами со смешанной кодовой базой. Даны советы по рефакторингу кода и функциональному программированию на Kotlin.

 Расстояние от острова Ява до острова Котлин составляет 9892 километра по прямой. Чтобы преодолеть его, не пользуясь воздушным транспортом, понадобится как минимум неделя. Если вы — опытный Java-разработчик, который решил перейти на Kotlin, вам потребуется примерно столько же времени. Вы обнаружите, что в Kotlin все делается по-другому, он требует иных подходов к программированию. Этот язык более функционален, у него больше возможностей, поэтому перенос кода ваших проектов с Java на Kotlin — отличная идея.

 Ваши гиды Дункан и Нэт уже проделали этот путь в 2015 году, и с тех пор помогли многим командам и отдельным разработчикам повторить его. Путешествуйте вместе с ними по проверенному маршруту, включающему такие промежуточные остановки, как переход от объектов JavaBeans к значениям, от коллекций Java к коллекциям Kotlin и от классов Java к классам Kotlin.

 Авторы подробно объясняют ключевые концепции, а затем показывают, как постепенно и безопасно перенести код Java в идиоматичный Kotlin, сохраняя при этом совместимость. В результате код становится проще, выразительнее и удобнее для редактирования. К концу путешествия вы будете уверены в том, что сможете перевести все свои Java-проекты на платформу Kotlin, освоите Kotlin с нуля и научитесь управлять смешанной языковой базой кода по мере ее развития.

 Взять знакомый всем старый добрый код Java и наблюдать за тем, как он постепенно превращается в лаконичный, четкий, выразительный и легкий в обслуживании код на языке Kotlin — замечательный способ выучить язык. Воспользуйтесь опытом, которым делятся Макгрегор и Прайс.

Pro Kotlin Web Apps from Scratch - August Lilleaas

2023
english

 Build production-grade web apps from scratch – without using frameworks – with Kotlin on the Java platform. You’ll learn how to use and compose libraries, how to choose between different libraries, and the benefits of explicit and straight-forward code, vs. the implicit magic, conventions, and inversion of control you often see in frameworks.


 The book teaches the Kotlin language by building production-ready Kotlin code. You’ll gain a deep understanding of the idiomatic use of the Kotlin language along with knowledge of how to apply Kotlin in production-grade web apps. The book also bridges the gap between building from scratch and using existing frameworks. For example, you’ll learn how to integrate Spring Security-based authentication in web apps written from scratch, so you can leverage existing tooling in your organization without having to take on the entire Spring framework. 

 The first section of the book sets up the base structure of your web app, such as routing, configuration files, and database migrations. The remaining chapters are broken into individual aspects of building production-ready web apps. Appendices at the end of the book explain how to use different libraries than the ones chosen in the main chapters, so you'll learn how to decouple your code from specific libraries, and choose between many different libraries to get the job done in your own web apps.

What You Will Learn

  • Compose libraries and manage boilerplate code using idiomatic and powerful Kotlin
  • Manage and query SQL databases without ORMs and mapping layers
  • Write resilient and change-proof tests in support of test-driven development practices
  • Create traditional, HTML-based web apps, APIs for JavaScript-based single-page web apps and native mobile apps
  • Manage parallelism and external service calls using Kotlin co-routines
  • Deploy to production using embedded servers, WAR files, and serverless approaches
  • Bridge the gap between custom-built apps and enterprise, using Spring Context and Spring Security

Who This Book Is For

 The expert developer who is ready to take full control of the tech stack, and use the Kotlin language, type system, and standard library, to ship production-ready web apps. Readers should have prior programming experience. Experience with Java or another JVM language is helpful.

Kotlin Multiplatform by Tutorials - Carlos Mota, Kevin D Moore, Saeed Taheri

2022
english

 If your goal is to leverage Kotlin to share code among your native apps, this is the book for you.

 Maintaining multiple native apps with duplicated code can be a time-consuming process. This duplication also increases the testing effort, eventually slowing down the project and increasing costs.

 You can use Kotlin Multiplatform to share code between your Android, iOS and desktop apps but there are multiple considerations. You should be able to develop the UI natively using the framework of your choice. Using the right frameworks can drastically reduce the UI development time and provide you with flexible APIs.

 At the same time, you need to figure out how Kotlin Multiplatform fits in with your current architecture and how you can access platform-specific APIs. Choosing the right architecture can make your app testable, maintainable and easy to work with.

 Then you need to figure out which layers of your app you can migrate to a shared module and how you can use different libraries to assist this migration. Finally, you should be able to publish and share your shared module so that you can use it across apps on multiple platforms.

 Head First Kotlin is a complete introduction to coding in Kotlin. This hands-on book helps you learn the Kotlin language with a unique method that goes beyond syntax and how-to manuals and teaches you how to think like a great Kotlin developer. You’ll learn everything from language fundamentals to collections, generics, lambdas, and higher-order functions. Along the way, you’ll get to play with both object-oriented and functional programming. If you want to really understand Kotlin, this is the book for you.

 Why does this book look so different?

 Based on the latest research in cognitive science and learning theory, Head First Kotlin uses a visually rich format to engage your mind rather than a text-heavy approach that puts you to sleep. Why waste your time struggling with new concepts? This multisensory learning experience is designed for the way your brain really works.

2021
русский

 Этот сборник рецептов охватывает широкий спектр тем, с которыми следует ознакомиться разработчику, планирующему перейти на язык Kotlin или желающему изучить его более глубоко. В начале книги описывается процесс установки и запуска Kotlin, затем обсуждаются фундаментальные особенности языка. Особое внимание уделено его объектно-ориентированным возможностям, которые могут показаться необычными разработчикам на других языках.

 Рецепты, собранные в разных главах по тематическому принципу, можно изучать в любом порядке, удобном читателю. Они дополняют друг друга, и каждый рецепт заканчивается ссылками на другие. Материал удобно структурирован: за  описанием каждой задачи следуют ее решение и развернутое обсуждение.

 Издание предназначено для разработчиков, знакомых с объектно-ориентированным программированием, особенно на Java или другом языке, основанном на JVM. Знание Java предпочтительно, но не обязательно.
