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.

It is a useful and practical way to navigate around an app, but perhaps even more than this, it is an extremely satisfying visual effect for the user. Also, as with RecyclerView, we can selectively load just the data required for the current page and perhaps the data for the previous and next pages.

The Android API, as you would have come to expect, has a number of solutions for achieving paging in a quite simple manner.

In this chapter, we will learn to do the following:

  • Achieve paging and swiping with images like you might find in a photo gallery app.
  • Implement paging and swiping with fragments, giving the potential to offer our users the ability to swipe their way through a selection of entire user interfaces, thereby giving our apps...
