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

  1. In this chapter, we looked at how to use simple Java arrays to store substantial amounts of data provided it is of the same type. We also used the ArrayList class, which is like an array with loads of extra features. Furthermore, we found out that both arrays and ArrayList instances are polymorphic, which means that a single array (or ArrayList) can hold multiple different objects as long as they are all derived from the same parent class.

    In addition, we learned about the HashMap class, which is also a data storage solution but allows access in different ways.

    In the next chapter, we will learn about the Adapter and RecyclerView classes to put our theory into practice and enhance the Note to Self app.
