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 the model-view-controller pattern

The model-view-controller pattern involves the separation of different aspects of our app into distinct parts called layers. Android apps commonly use the model-view-controller pattern. A pattern is simply a recognized way to structure our code and other application resources such as layout files, images, databases, and so on.

Patterns are useful to us because by conforming to a pattern, we can be more confident we are doing things right and are less likely to have to undo lots of hard work because we have coded ourselves into an awkward situation.

There are many patterns in computer science but an understanding of model-view-controller (MVC) will be enough to create some professionally built Android apps.

We have been partly using MVC already, so let's look at each of the three layers in turn:

  • Model: Model refers to the data that drives our app and any logic/code that specifically manages it and makes it available...
