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.

Repeating code with loops

Here we will learn how to repeatedly execute portions of our code in a controlled and precise way by looking at several types of loops in Java. These include while loops, do while loops, and for loops. We will also learn about the most appropriate situations to use the different types of loops.

It would be completely reasonable to ask what loops have to do with programming. But they are exactly what the name implies. They are a way of repeating the same part of the code more than once – or looping over the same part of code although potentially for a different outcome each time.

This can simply mean doing the same thing until the code being looped over (iterated) prompts the loop to end. It could be a predetermined number of iterations as specified by the loop code itself. It might be until a predetermined situation or condition is met. Or it could be a combination of more than one of these things. Along with if, else, and switch, loops are part...
