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.

It isn't an optional extra like a racing spoiler on a car or pulsating LEDs in a gaming PC. It's part of Java and therefore Android as well.

Let's find out a little bit more.

What is OOP exactly?

OOP is a way of programming that involves breaking our requirements down into chunks that are more manageable than the whole.

Each chunk is self-contained yet potentially reusable by other programs, while working together as a whole with the other chunks.

These chunks are what we refer to as objects. When we plan/code an object, we do so with a class. A class can be thought of as the blueprint of an object.

We implement an object of a class. This is called an instance of a class. Think about a house blueprint. You can't live in it, but you can build...
