Android Studio 4.0 Development Essentials - Kotlin Edition

By: Neil Smyth

Overview of this book

Kotlin as an Android-compatible programming language is becoming increasingly popular. Fully updated for Android Studio 4.0, this book will teach you the skills necessary to develop Android-based applications using Kotlin. Starting with the basics, this book outlines the steps necessary to set up Android development and testing environments, and goes on to introduce you to programming in Kotlin. You’ll practice Java to Kotlin code conversion and explore data types, operators, expressions, loops, functions, as well as the basics of OOP in Kotlin. You’ll then learn about Android architecture components and advanced topics, such as intents, touchscreen handling, gesture recognition, multi-window support integration, and biometric authentication. As you make progress, you’ll explore Android Studio 4.0’s key features, including layout editor, direct reply notifications, and dynamic delivery. You’ll also delve into Android Jetpack and create a sample app project using ViewModel, the Android Jetpack component. Finally, you will upload your app to Google Play Console and model the build process using Gradle. By the end of this Android book, you’ll be fully prepared to develop applications using Android Studio 4.0 and Kotlin.

95.2 Adding Dynamic Feature Support to the Project

Before embarking on the implementation of the app, two changes need to be made to the project to add support for dynamic features. Since the project will be making extensive use of the Play Core Library, a directive needs to be added to the build configuration to include this library. Within Android Studio, open the app level build.gradle file (Gradle Scripts -> build.gradle (Module: app)), locate the dependencies section and add the Play Core Library as follows (keeping in mind, as always, that a newer version of the library may now be available):

.

.

dependencies {

.

.

    implementation 'com.google.android.play:core:1.7.3'

.

.

}

Once a dynamic feature module has been downloaded, it is most likely that immediate access to code and resource assets that comprise the feature will be required by the user. By default, however, newly installed feature modules are not available...
