Android Programming for Beginners

By: John Horton, Paresh Mayani

Overview of this book

Android is the most popular OS in the world. There are millions of devices accessing tens of thousands of applications. It is many people's entry point into the world of technology; it is an operating system for everyone. Despite this, the entry-fee to actually make Android applications is usually a computer science degree, or five years’ worth of Java experience. Android Programming for Beginners will be your companion to create Android applications from scratch—whether you’re looking to start your programming career, make an application for work, be reintroduced to mobile development, or are just looking to program for fun. We will introduce you to all the fundamental concepts of programming in an Android context, from the Java basics to working with the Android API. All examples 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, make location-aware apps with Google Maps integration, and store your user’s data with SQLite. In addition, you’ll see how to make your apps multilingual, capture images from a device’s camera, 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.

FAQ


  1. So is Android not really an operating system, but just a virtual machine? And are all phones and tablets really Linux machines?

    No, all the different subsystems of an Android device, which includes Linux, the DVM, and the libraries and drivers together, are what make up the Android operating system.

  2. I still don't understand all of these technical terms, such as DVM, object-oriented, APK, and so on. Should I reread this chapter?

    No, that isn't necessary, as we just need to introduce this jargon, and we will be revisiting them all as well as clarifying them as the book progresses. You just need to understand the following:

    • We will be writing Java code and creating other resources

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

Now, you are good to go and can move on to Chapter 2, Java – First Contact.
