Introduction
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 Java programming language.
Beginning with the basics, this book provides an outline of the steps necessary to set up an Android development and testing environment. An overview of Android Studio is included covering 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.
Chapters are also included covering the Android Architecture Components including 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 covered 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 are also covered in detail including the Layout Editor, the ConstraintLayout and ConstraintSet classes, MotionLayout Editor, view binding, constraint chains, barriers and direct reply notifications.
Chapters also cover advanced features of Android Studio such as App Links, Dynamic Delivery, Gradle build configuration, and submitting apps to the Google Play Developer Console.
Assuming you already have some Java programming experience, are ready to download Android Studio and the Android SDK, have access to a Windows, Mac or Linux system and ideas for some apps to develop, you are ready to get started.

Setting up an Android Studio Development Environment
Before any work can begin on the development of an Android application, the first step is to configure a computer system to act as the development platform. This involves a number of steps consisting of installing the Android Studio Integrated Development Environment (IDE) which also includes the Android Software Development Kit (SDK) and OpenJDK Java development environment.
This chapter will cover the steps necessary to install the requisite components for Android application development on Windows, macOS and Linux based systems.
2.1 System Requirements
Android application development may be performed on any of the following system types:
Windows 8/10 64-bit
macOS 10.14 or later, Intel Core, AMD, or Apple silicon
Chrome OS device with Intel i5 or higher
Linux systems with version 2.31 or later of GNU C Library (glibc)
Minimum of 8GB of RAM
Approximately 8GB of available disk space
1280 x 800 minimum screen resolution
2.2 Downloading the Android Studio Package
Most of the work involved in developing applications for Android will be performed using the Android Studio environment. The content and examples in this book were created based on Android Studio Arctic Fox 2020.3.1 using the Android 11.0 (R) API 30 SDK which, at the time of writing, are the current versions.
Android Studio is, however, subject to frequent updates so a newer version may have been released since this book was published.
The latest release of Android Studio may be downloaded from the primary download page which can be found at the following URL:
https://developer.android.com/studio/index.html
If this page provides instructions for downloading a newer version of Android Studio it is important to note that there may be some minor differences between this book and the software. A web search for Android Studio Arctic Fox should provide the option to download the older version in the event that these differences become a problem. Alternatively, visit the following web page to find Android Studio Arctic Fox in the archives:

2.3 Installing Android Studio
Once downloaded, the exact steps to install Android Studio differ depending on the operating system on which the installation is being performed.
2.3.1 Installation on Windows
Locate the downloaded Android Studio installation executable file (named android-studio--windows. exe) in a Windows Explorer window and double-click on it to start the installation process, clicking the Yes button in the User Account Control dialog if it appears.
Once the Android Studio setup wizard appears, work through the various screens to configure the installation to meet your requirements in terms of the file system location into which Android Studio should be installed and whether or not it should be made available to other users of the system. When prompted to select the components to install, make sure that the Android Studio and Android Virtual Device options are all selected.
Although there are no strict rules on where Android Studio should be installed on the system, the remainder of this book will assume that the installation was performed into C:\Program Files\Android\Android Studio and that the Android SDK packages have been installed into the users AppData\Local\Android\sdk sub-folder. Once the options have been configured, click on the Install button to begin the installation process.
