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.

Chapter 3. Exploring Android Studio and the Project Structure

In this chapter, we will create and run two more Android projects. The purpose of these exercises is to explore more deeply Android Studio and the structure of Android projects.

When we build our apps ready for deployment, the code and the resource files need to be packed away in the APK file—just so. Therefore, all the layout files and other resources, which we will be looking at soon, need to be in the correct structures.

Fortunately, Android Studio handles this for us when we create a project from a template. However, we still need to know how to find and amend these files, how to add our own and sometimes remove the files created by Android Studio, and how the resource files are interlinked—sometimes with each other and sometimes with the Java code (auto-generated Java code as well as our own).

Along with understanding the composition of our projects, it will also be beneficial to make sure we get the...
