Android Programming for Beginners

By: John Horton, Paresh Mayani

Overview of this book

Android is the most popular OS in the world. There are millions of devices accessing tens of thousands of applications. It is many people's entry point into the world of technology; it is an operating system for everyone. Despite this, the entry-fee to actually make Android applications is usually a computer science degree, or five years’ worth of Java experience. Android Programming for Beginners will be your companion to create Android applications from scratch—whether you’re looking to start your programming career, make an application for work, be reintroduced to mobile development, or are just looking to program for fun. We will introduce you to all the fundamental concepts of programming in an Android context, from the Java basics to working with the Android API. All examples 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, make location-aware apps with Google Maps integration, and store your user’s data with SQLite. In addition, you’ll see how to make your apps multilingual, capture images from a device’s camera, 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 17. Sound FX and Supporting Different Versions of Android

In this chapter, you will learn how to load and play sound effects (FX) on Android. As the sound part of the Android API has recently been updated, this is also a good opportunity to look at a strategy for supporting different versions of Android. Throughout the book, we have been writing apps that run on 95% of devices by default, but there are times when we want to support more devices. Also, it is useful to be able to future-proof our apps a bit when we know that the code we write will eventually not work on new devices. This chapter includes the following topics:

  • How to code for different versions of Android in the same app

  • How does the SoundPool class work

  • The sound FX mini app

  • How to add sound to the Note To Self app
