Overview of this book

Android is the most popular mobile operating system in the world and Kotlin has been declared by Google as a first-class programming language to build Android apps. With the imminent arrival of the most anticipated Android update, Android 10 (Q), this book gets you started building apps compatible with the latest version of Android. It adopts a project-style approach, where we focus on teaching the fundamentals of Android app development and the essentials of Kotlin by building three real-world apps and more than a dozen mini-apps. The book begins by giving you a strong grasp of how Kotlin and Android work together before gradually moving onto exploring the various Android APIs for building stunning apps for Android with ease. You will learn to make your apps more presentable using different layouts. You will dive deep into Kotlin programming concepts such as variables, functions, data structures, Object-Oriented code, and how to connect your Kotlin code to the UI. You will learn to add multilingual text so that your app is accessible to millions of more potential users. You will learn how animation, graphics, and sound effects work and are implemented in your Android app. By the end of the book, you will have sound knowledge about significant Kotlin programming concepts and start building your own fully featured Android apps.

Summary


In this chapter, we built aesthetically pleasing CardView layouts and put them in a ScrollView layout so that the user can swipe through the content of the layout a bit like browsing a web page. To conclude the chapter, we launched a tablet emulator and saw that we are going to need to get smart with how we design our layouts if we want to cater for different device sizes and orientations. In Chapter 24, Design Patterns, Multiple Layouts, and Fragments, we will begin to take our layouts to the next level and learn how to cope with such a diverse array of devices by using Android Fragments.

Before we do so, however, it will serve us well to learn more about Kotlin and how we can use it to control our UI and interact with the user. This will be the focus of the next seven chapters.

Of course, the elephant in the room at this point is that, despite learning lots about layouts, project structure, the connection between Kotlin and XML, and much more besides, our UIs, no matter how pretty...
