Android Programming for Beginners - Second Edition

By: John Horton

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.

Frequently asked questions


Q1) So, Android isn't really an operating system. Is it just a virtual machine and all the phones and tablets are really Linux machines?

A) No, all the different subsystems of an Android device, which include Linux, the DVM, and the libraries and drivers together, are what makes up the Android operating system.

Q2) I still don't understand all these technical terms, such as DVM, object-oriented and APK. Should I re-read this chapter?

A) No, this isn't necessary, as we just need to introduce this jargon and will be revisiting it all, as well as clarifying it as the book progresses. If you understand the following two points, you are ready to proceed to Chapter 2, First Contact: Java, XML and the UI Designer:

  • We will be writing Java code and creating other resources

  • Android Studio with the help of the JDK and will turn this code and resources into real Android apps.
