Android Programming for Beginners

By: John Horton, Paresh Mayani

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.

FAQ


  1. As each Fragment is an entirely separate class, how will they communicate with each other?

    We will solve this problem with a practical use of Java that you have already learned about—interfaces—along with some other tools as well, starting in the next chapter.

  2. The other missing link is that, if all these fragments are fully functioning independent controllers, then you need to learn a bit more about how we would implement our model layer. If we simply have ArrayList, like with Note To Self, where will it go? How would we share it between fragments (assuming both fragments need access to the same data)?

    There is an entirely more elegant solution that we can use to create a model layer (both the data itself and the code to maintain the data). We can use the Java singleton, and we will do so in the next chapter.
