Chapter 23. Android Sound Effects and the Spinner Widget

In this chapter, we will study the SoundPool class and the different ways we can use it depending on whether we just want to play sounds or go further and keep track of the sounds we are playing. Then, we will put everything we will have learned into action by producing a cool sound demo app, which will also introduce us to a new UI widget: the spinner.

In this chapter, we will do the following:

• Learn how to use the Android SoundPool class
• Code a sound-based app using SpinnerView

Let's get started.
