Overview of this book

Popularity of Kotlin as an Android-compatible language keeps growing every day. This book will help you to build your own Android applications using Kotlin. Android Studio 3.5 Development Essentials Kotlin Edition first teaches you to install Android development and test environment on different operating systems. Next, you will create an Android app and a virtual device in Android studio, and install an Android application on emulators. You will test apps on physical android devices, then study Android Studio code editor, Android architecture, and the anatomy of an Android app. The focus then shifts to Kotlin language. You’ll get an overview of Kotlin language and practice converting code from Java to Kotlin. You’ll also explore Kotlin data types, operators, expressions, loops, functions, and the basics of OOP concept in Kotlin. This book will then cover Android Jetpack and how to create an example app project using ViewModel component, as well as advanced topics such as views and widgets implementation, multi-window support integration, and biometric authentication.

When an activity in multi-window mode launches another activity within the same task stack, the new activity replaces the originating activity within the split-screen or freeform window (the user returns to the original activity via the back button).

When launched into a new task stack in split-screen mode, however, the second activity will appear in the window adjacent to the original activity, allowing both activities to be viewed simultaneously. In the case of freeform mode, the launched activity will appear...
