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

We have learned about the Android lifecycle and how the operating system calls set methods at set times.

We have also seen that it is not only us that can call our code. The operating system can also call the code contained within the methods we have overridden. By adding the appropriate code into the various overridden lifecycle methods, we can be sure that the right code will be executed at the right time.

What we need to do now is learn how to write some more Java code. In the next chapter, we'll start to focus on Java, and because we have such a good grounding already on Android, we will have no problem practicing and using everything we learn.
