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.

Chapter 21: Threads and Starting the Live Drawing App

In this chapter, we will get started on our next app. This app will be a kid's drawing app where the user can draw on the screen with their finger. This drawing app will be slightly different, however. The lines that the user draws will comprise particle systems that explode into thousands of pieces. We will call the project Live Drawing.

To achieve this, we will do the following:

  • Get started with the Live Drawing app
  • Learn about real-time interaction, sometimes called a game loop
  • Learn about threads
  • Code a real-time system ready to draw with in the next chapter

Let's get started.
