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.

Themes and material design


Creating a new theme, technically speaking, is very easy, and we will see how to do it in a minute. From an artistic point of view, however, it is more difficult. Choosing which colors work well together, let alone suit your app and the imagery, is much more difficult. Fortunately, we can turn to material design for help.

Material design has guidelines for every aspect of UI design and all the guidelines are very well documented. Even the sizes for text and padding that we used for the CardView project were all taken from material design guidelines.

Not only does material design make it possible for you to design your very own color schemes, but it also provides palettes of ready-made color schemes.

Note

This book is not about design, although it is about implementing design. To get you started, the goal of our designs might be to make our UI unique and to stand out at the exact same time as making it comfortable for, even familiar to, the user.
