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.

Java is everywhere

The core Java fundamentals that we are about to learn apply when working within classes that we inherit from (such as Activity/AppCompatActivity), as well as classes that we write ourselves (as we will start to do in Chapter 10, Object-Oriented Programming).

As it is more logical to learn the basics before we write our own classes, we will be using the extended Activity class, AppCompatActivity, to add lots of different code in a whole bunch of mini-projects in the next few chapters to learn and practice Java. We will use Log and Toast again to see the results of our coding. In addition, we will use more methods that we will write ourselves (called from buttons), as well as the overridden methods of the Activity class to trigger the execution of our code. We will finally get the full details on methods in Chapter 9, Java Methods.

When, however, we move onto Chapter 10, Object-Oriented Programming, and start to write our own classes, as well as understand more about how...
