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.

Chapter 12. Having a Dialogue with the User

In this chapter, we will see how to present a user with a pop-up dialog window. We can then put all we know into the first phase of our first app, Note To Self. You will learn about new Android and Java features in this chapter and the next five chapters as well, and we will use your newly acquired knowledge to enhance the Note To Self app each time.

In each chapter, we will also build a selection of mini apps that are separate from this main app. So, this chapter holds the following in store for you:

  • How to implement a simple app with a pop-up dialog box

  • How to add DialogFragments to start the Note To Self app

  • How to add resources such as Strings and graphics to a project

  • How to use Android naming conventions for the first time to make our code more readable

  • How to implement more complex dialog boxes to capture input from the user

Let's get started.
