Android Programming for Beginners - Second Edition

By: John Horton

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.

So far, on a few occasions, I have asked that you accept a simplified explanation to offer a fuller explanation at a more appropriate time, like I have with classes and methods.

Having said that, the Java and Android communities are full of people who speak in technical terms, and to join in and learn from these communities, you need to understand the terms they use. So, the approach this book takes is to learn a concept or appreciate an idea using entirely plain-speaking language, but at the same time introduce the jargon/technical term as part of the learning.

Java syntax is the way we put together the language elements of Java to produce code that works in the Dalvik virtual machine. The Java syntax is a combination of the words we use and...
