By: John Horton

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.

Introducing NavigationView

What's so great about NavigationView? Well, the first thing that might catch your eye is that it can be made to look extremely stylish. Take a look at this next screenshot, which shows off a NavigationView in action in the Google Play app:

To be honest, right from the start, ours is not going to be as fancy as the one in the Google Play app. But the same functionality will be present in our app.

What else is neat about this UI is the way that it slides to hide/reveal itself when required. It is because of this behavior that it can be a significant size, making it extremely flexible with regard to the options that can be put on it, and when the user is finished with it, it completely disappears, like a drawer.

I suggest trying the Google Play app now and seeing how it works if you haven't already.

You can slide your thumb/finger from the left-hand edge of the screen...
