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.

Starting the Simple Database project

Create a new project in Android Studio. Call it Age Database, use the Navigation Drawer Activity template, and leave all the Activity and layout names at their defaults. Before we do anything else, it is well worth running the app on an emulator to see how much has been auto-generated as part of this template, as can be seen in the following screenshot:

At first glance, it is just a plain old layout with a TextView. But swipe from the left edge, or press the menu button, and the Navigation Drawer reveals itself:

Now we can modify the options and insert a Fragment (with layout) for each option. To understand how it works, let's examine the auto-generated code.
