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.

Frequently asked questions

  1. I know how to animate widgets now but what about shapes or images that I create myself?

    An ImageView can hold any image you like. Just add the image to the drawable folder and then set the appropriate src attribute on the ImageView widget. You can then animate whatever image is being shown in the ImageView.

  2. But what if I want more flexibility than this, such as for a drawing app or even a game?

    To implement this kind of functionality, we will need to learn about another general computing concept (threads) as well as some more Android classes (such as Paint, Canvas, and SurfaceView). We will learn how to draw anything from a single pixel to shapes and then move them around the screen starting in the next chapter, Chapter 20, Drawing Graphics.
