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.

Real-world apps

So far, we have designed one fairly significant app and a dozen or more mini apps. Some we designed for tablets, but we designed most of them on the Nexus 5 phone. Also, most of the screenshots in this book have been on the Nexus 5 emulator.

Of course, in the real world, our apps need to work well on any device and must be able to handle what happens when in either portrait or landscape view (on all devices).

Furthermore, it is often not enough for our apps to just work and look OK on different devices. Often, our apps will need to behave differently and appear with a significantly different UI based on whether the device is a phone, a tablet, or in the landscape/portrait orientation.

Note

Android has supported apps for large screen TV's for some time now, and in 2015, it introduced the Wear API to build apps for Android watches. We will not be covering these two most-extreme cases in this book.

Take a look at this screenshot of the BBC news app running on an Android phone...
