Overview of this book

Do you want to make a career in programming but don’t know where to start? Do you have a great idea for an app but don't know how to make it a reality? Or are you worried that you’ll have to learn Java programming to become an Android developer? Look no further! This new and expanded third edition of Android Programming for Beginners will be your guide to creating Android applications from scratch. The book starts by introducing you to all the fundamental concepts of programming in an Android context, from the basics of Java to working with the Android API. You’ll learn with the help of examples that use up-to-date API classes and are created within Android Studio, the official Android development environment that helps supercharge your mobile application development process. After a crash course on the key programming concepts, you’ll explore Android programming and get to grips with creating applications with a professional-standard UI using fragments and storing user data with SQLite. This Android Java book also shows you how you can make your apps multilingual, draw on the screen with a finger, and work with graphics, sound, and animations. By the end of this Android programming book, you'll be ready to start building your own custom applications in Android and Java.

Each chapter will also build a selection of smaller apps that are separate from this main app. So, what does this chapter hold in store for you? Well, we will cover the following topics:

  • Implementing a simple app with a pop-up dialog box
  • Using the DialogFragment class to begin the Note to Self app
  • Adding string resources in our projects instead of hardcoding text in our layouts
  • Using Android naming conventions for the first time to make our code more readable
  • Implementing more complex dialog boxes to capture input from the user
