Overview of this book

Do you want to make a career in programming but don’t know where to start? Do you have a great idea for an app but don't know how to make it a reality? Or are you worried that you’ll have to learn Java programming to become an Android developer? Look no further! This new and expanded third edition of Android Programming for Beginners will be your guide to creating Android applications from scratch. The book starts by introducing you to all the fundamental concepts of programming in an Android context, from the basics of Java to working with the Android API. You’ll learn with the help of examples that use up-to-date API classes and are created within Android Studio, the official Android development environment that helps supercharge your mobile application development process. After a crash course on the key programming concepts, you’ll explore Android programming and get to grips with creating applications with a professional-standard UI using fragments and storing user data with SQLite. This Android Java book also shows you how you can make your apps multilingual, draw on the screen with a finger, and work with graphics, sound, and animations. By the end of this Android programming book, you'll be ready to start building your own custom applications in Android and Java.

Of course, with all this talk of sound effects, we need some actual sound files. You can make your own with Bfxr (explained next) or use the ones supplied. The sound effects for this app are in the download bundle in the assets folder of the Chapter 23/Sound Demo folder. But you might like to make your own.

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.

Note

Note that the sound effects for the sound demo app are supplied to you in the Chapter 23/assets folder. You don't have to create your own sound effects unless you want to. 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:
