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.

We will first create a new Activity for our Settings screen and see what effect that has on the AndroidManifest.xml file. We will then create a very simple layout for our Settings screen and add the Java code to switch from MainActivity to the new one. We will, however, defer wiring up our Settings screen with Java until we have learned how to save the settings to disk. We will do this later this chapter and then come back to the Settings screen to make it persist.

First, let's create that new Activity. We will call it SettingsActivity.

Creating the SettingsActivity

This will be a screen where the user can turn the decorative divider between each note in the RecyclerView on or off. This will not be the most comprehensive settings screen, but it will be a useful exercise, and we will...
