Overview of this book

Are you trying to start a career in programming, but haven't found the right way in? Do you have a great idea for an app, but don't know how to make it a reality? Or maybe you're just frustrated that in order to learn Android, you must know Java. If so, then this book is for you. This new and expanded second edition of Android Programming for Beginners will be your companion to create Android Pie applications from scratch. We will introduce you to all the fundamental concepts of programming in an Android context, from the basics of Java to working with the Android API. All examples use the up-to-date API classes, and are created from within Android Studio, the official Android development environment that helps supercharge your application development process. After this crash course, we'll dive deeper into Android programming and you'll learn how to create applications with a professional-standard UI through fragments and store your user's data with SQLite. In addition, you'll see how to make your apps multilingual, draw to the screen with a finger, and work with graphics, sound, and animations too. By the end of this book, you'll be ready to start building your own custom applications in Android and Java.

Chapter 23. Supporting Different Versions of Android, Sound Effects, and the Spinner Widget

In this chapter, we will learn about how we can detect and handle different versions of Android. We will then be able to study the SoundPool class and the different ways we can use it depending on the Android version the app is running on. At this point, we can then put everything we have learned into producing cool sound demo apps, which will also introduce us to a new UI widget – the Spinner.

In summary, in this chapter, we will cover the following topics:

  • How to handle different versions of Android

  • How to use the Android SoundPool class

  • Coding a sound-based app by using SpinnerView

Let's get started.
