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.

Of course, with all this talk of sound effects, we need some actual sound files. You can make you own with BFXR (as explained in the next section) or use the ones supplied. The sound effects for this app are in the download bundle, and can be found in the assets folder of the Chapter23/Sound Demo folder.

Making sound effects

There is an open source app called BFXR that allows us to make our own sound effects. Here is a very fast guide to making your own sound effects using BFXR. Grab a free copy from www.bfxr.net.

Tip

Note that the sound effects for the Sound demo app are supplied to you in the Chapter23/assets folder. You don't have to create your own sound effects unless you want to, but it is still worth getting this free software and learning how to use it.

Follow the simple instructions on the website to set it up. Try out a few of these things to make cool sound effects:
