Android Programming for Beginners

Overview of this book

Android is the most popular OS in the world. There are millions of devices accessing tens of thousands of applications. It is many people's entry point into the world of technology; it is an operating system for everyone. Despite this, the entry-fee to actually make Android applications is usually a computer science degree, or five years’ worth of Java experience. Android Programming for Beginners will be your companion to create Android applications from scratch—whether you’re looking to start your programming career, make an application for work, be reintroduced to mobile development, or are just looking to program for fun. We will introduce you to all the fundamental concepts of programming in an Android context, from the Java basics to working with the Android API. All examples 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, make location-aware apps with Google Maps integration, and store your user’s data with SQLite. In addition, you’ll see how to make your apps multilingual, capture images from a device’s camera, 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.

A simplified explanation of the Android lifecycle

If you have ever used an Android device, you have probably noticed it works quite differently than many other operating systems. For example, you can be using an app, say you're checking what people are doing on Facebook. Then you get an e-mail notification and you tap the e-mail icon to read it. Mid-way through reading the e-mail you might get a Twitter notification, and because you're waiting on important news from someone you follow, you interrupt your e-mail reading and change apps to Twitter, with one touch.

After reading the tweet, you fancy a game of Angry Birds, but mid-way through the first daring fling you suddenly remember that Facebook post. So you quit Angry Birds and tap the Facebook icon.

Then you resume Facebook, probably at the same point you left it. You could have resumed reading the e-mail, decided to reply to the tweet, or started an entirely new app.

All this backwards and forwards takes quite a lot of management...
