Android Studio 4.0 Development Essentials - Java Edition

By: Neil Smyth

Overview of this book

Android rolls out frequent updates to meet the demands of the dynamic mobile market and to enable its developer community to lead advancements in application development. This book focuses on the updated features of Android Studio (the fully integrated development environment launched by Google) to build reliable Android applications using Java. The book starts by outlining the steps necessary to set up an Android development and testing environment. You’ll then learn how to create user interfaces with the help of Android Studio Layout Editor, XML files, and by writing the code in Java. The book introduces you to Android architecture components and advanced topics such as intents, touchscreen handling, gesture recognition, multi-window support integration, and biometric authentication, and lets you explore key features of Android Studio 4.0, including the layout editor, direct reply notifications, and dynamic delivery. You’ll also cover Android Jetpack in detail and create a sample app project using the ViewModel component. Finally, you’ll upload your app to the Google Play Console and handle the build process with Gradle. By the end of this book, you’ll have gained the skills necessary to develop applications using Android Studio 4.0 and Java.

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app)), locate the dependencies section and add the Play Core Library as follows (keeping in mind, as always, that a newer version of the library may now be available):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...
