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.

Supporting multiple versions of Android

Most of the time throughout this book, we haven't paid any attention to supporting older Android devices because it did not seem worthwhile. The main reason being that all the up-to-date parts of the API we have been using work on such a high percentage of devices (in excess of 95%). Unless you intend to carve out a niche in apps for ancient Android relics, this seems like a sensible approach. With regard to playing sounds, however, there have been some fairly recent modifications to the Android API.

Actually, this isn't immediately a big deal because devices newer than this can still use the old parts of the API. However, it is good practice to specifically handle these differences in compatibility because eventually, one day, the older parts might not work on newer versions of Android.

The main reason for discussing this here is that the slight differences in pre- and post-android Lollipop sound handling give us a good excuse to see how...
