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.

We have, to a small extent, created interaction between our Java code and our UI. We have called our methods by setting the onClick attribute and we have loaded our UI layouts using the setContentView method. We haven't, however, really made a proper connection between our UI and our Java code.

What we really need to do now is to bring these things together, so we can begin to display and manipulate our data using the Android UI. To achieve this, we need to understand a bit more about classes.

Classes have been lurking in our code since Chapter 1, Beginning Android and Java, and we have even used them a bit. Up until now, however, we haven...
