Overview of this book

Android Studio is an Integrated Development Environment based on the JetBrains IntelliJ IDEA. It offers developers a unique platform to design and develop Android apps using various developer tools. Fully updated for Android Studio Arctic Fox, the goal of this book is to teach the skills necessary to develop Android-based applications using the Kotlin programming language. This book begins with an outline of the steps necessary to set up an Android development and testing environment, followed by an introduction to programming in Kotlin which includes data types, control flow, functions, lambdas, and object-oriented programming. An overview of Android Studio covers areas such as tool windows, the code editor, and the layout editor tool. An introduction to the architecture of Android is followed by an in-depth look at the design of Android applications and user interfaces using the Android Studio environment. Early chapters detail Android architecture components such as view models, lifecycle management, Room database access, the Database Inspector, app navigation, live data, and data binding. More advanced topics such as intents are also covered, as are touch screen handling, gesture recognition, and the recording and playback of audio. This edition of the book also covers printing, transitions, cloud-based file storage, and foldable device support. The concepts of material design are also discussed in detail, including the use of floating action buttons, Snackbars, tabbed interfaces, card views, navigation drawers, and collapsing toolbars. Other key features of Android Studio Arctic Fox and Android taught in this book include the Layout Editor, the ConstraintLayout and ConstraintSet classes, MotionLayout Editor, view binding, constraint chains, barriers, and direct reply to notifications. Chapters also explore more advanced features of Android Studio such as app links, dynamic delivery, Gradle build configuration, and submitting apps to the Google Play developer console.

The layout for the detail pane (the screen that is displayed when the user selects an item from the primary list) is contained within the activity_website_detail.xml file which, in turn, contains a FrameContainerView instance which is used to display the actual detail pane content. If the app is displaying in single-pane mode, the frame container will display the layout contained in the fragment_website_detail.xml file, while multi-pane mode will display the fragment_website_detail.xml (sw600dp) layout.

The template layout provided by Android Studio for the fragment_website_detail.xml comprises a Coordinator layout containing an app bar, toolbar, floating action button, and a text view. For this example, all we need to display is a WebView, so open this file and delete all of the views from the layout with the exception of the website_detail_container view. The easiest way to do this is to select all of the unwanted views in the Component Tree as shown...
