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.

In one thread of a story, we might have the primary character battling the enemy on the frontline, while in another, the thread shows that the soldier's family are getting by, day to day. Of course, a story doesn't have to have just two threads. We could introduce a third thread. Perhaps the story also tells about the politicians and military commanders making decisions. And these decisions then subtly, or not so subtly, affect what happens in the other threads.

Programming threads is just like this. We create parts/threads in our program that control different aspects for us. In Android, threads are especially useful when we need to ensure that a task does not interfere with the main (UI) thread of the app, or if we have a background task that takes a long time to complete and must not interrupt the main thread of execution. We introduce threads to represent these different...
