Review

"The authors use a practical approach with good sample apps and detailed step-by-step instructions that are easy to follow. This second edition of the book has been updated to Android 13 and the latest Android Studio. All screenshots are new and updated, some useful diagrams have been added, and each chapter starts with an enumeration of the topics covered. This book is for people without prior experience with Android app development; however, knowledge of the Kotlin programming language is required.

In summary, an excellent book to get started with modern Android app development updated to the latest version of Android and Kotlin."

Juan C Catalan, Senior Principal Software Engineer, Medtronic

"I really liked the book; it has everything you need to have a really good basis to start building your own apps, such as the Gradle build system, UI with XML and Jetpack Compose, Animations, Navigation, Network Calls, Coroutines, Recycler View, Permissions, Services, WorkManager, Notifications, Persistence, Dependency Injection, Testing, and so on, and it also teaches you how to publish your app to the Play Store.

The book is simple to understand, it has illustrations, diagrams, code snippets, and examples.

It really has everything you need to get you started on the right foot.

I highly recommend it."

David Caplette, Senior Software Engineer at EPAM Systems

“This book offers beginners a detailed roadmap to Android app development. It starts with setting up an Android Studio project and ends with publishing the app on the Store.
