Overview of this book

Do you want to make a career in programming but don’t know where to start? Do you have a great idea for an app but don't know how to make it a reality? Or are you worried that you’ll have to learn Java programming to become an Android developer? Look no further! This new and expanded third edition of Android Programming for Beginners will be your guide to creating Android applications from scratch. The book starts by introducing you to all the fundamental concepts of programming in an Android context, from the basics of Java to working with the Android API. You’ll learn with the help of examples that use up-to-date API classes and are created within Android Studio, the official Android development environment that helps supercharge your mobile application development process. After a crash course on the key programming concepts, you’ll explore Android programming and get to grips with creating applications with a professional-standard UI using fragments and storing user data with SQLite. This Android Java book also shows you how you can make your apps multilingual, draw on the screen with a finger, and work with graphics, sound, and animations. By the end of this Android programming book, you'll be ready to start building your own custom applications in Android and Java.

Summary

Now we have added the ability to hold multiple notes and implemented the ability to display them.

We achieved this by learning about and using the RecyclerAdapter class, which implements the Adapter interface, which allows us to bind together RecyclerView and ArrayList, allowing the seamless display of data without us (the programmer) having to worry about the complex code that is part of these classes and that we don't even see.

In the next chapter, we will start with making the user's notes persist when they quit the app or switch off their device. In addition, we will create a settings screen and see how we can make the settings persist as well. We will use different techniques to achieve each of these goals.
