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.

Summary


In this chapter, we have seen and implemented a common user interface design with dialog windows by using the DialogFragment class.

We went a step further when we started the Note to self app by implementing more complicated dialogs that can capture information from the user. We saw that DialogFragment enables us to have any UI we like in a dialog box.

In the next chapter, we will begin to deal with the obvious problem whereby the user can only have one note by exploring Java arrays and their close cousin, ArrayList, as well as another data-related class, Map.
