Android Programming for Beginners

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.

Our first working Fragment mini app

Let's build a Fragment in its simplest possible form so that we can understand what is going on before in later chapters we start producing Fragments all over the place.

Tip

I urge all readers to go through and actually build this project. There is a lot of jumping around from file to file and just reading alone can make it seem more complex than it really is. You can copy and paste the code from the download bundle but please also follow the steps and create your own projects and classes. Fragments are not too tough but their implementation, like there name suggests is a little fragmented.

Create a new project called Simple Fragment using the same default settings as always. Note that there is the option to create a project with Fragment, but you will learn more about them by doing things from scratch.

Switch to activity_main.xml and delete the default Hello world! widget. Now, make sure that the RelativeLayout root is selected by clicking on it in...
