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.

Publishing


You easily know enough to design your own app. You could even just make some modifications and add lots of new features to one of the apps from the book.

I decided not to do a step-by-step guide to publishing on Google's Play store because the steps are not complicated. They are, however, quite in-depth and a little laborious. Most of the steps involve entering personal information and images about you and your app. Such a tutorial would read something like the following:

  1. Fill this text box.

  2. Now, fill that text box.

  3. Upload this image.

  4. And so on.

Not much fun or use.

To get started, you just need to visit https://play.google.com/apps/publish and pay a modest fee (around $25) depending on your region's currency. This allows you to publish apps for life.

Note

If you want a checklist for publishing, take a look at the following URL: https://developer.android.com/distribute/best-practices/launch/launch-checklist.html. You will find the process intuitive (if very drawn out).
