By: John Horton

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.

Running Note to Self in German or Spanish

Run the app to see whether it is working as normal. Now we can change the localization settings to see it in Spanish. Different devices vary slightly in how to do this, but the Pixel 3 emulator options are as follows:

  1. Choose Settings | System | Languages and input | Add a language. Next, select Español and you will then be able to switch between Spanish and English from a list.
  2. Left-click and drag Español (Estados Unidos) so that it is at the top of the list.

Congratulations, your emulator is now defaulting to Spanish. Once you are done with this chapter, you can drag your preferred language back to the top of the list.

Now you can run the app in the usual way. Here are some screenshots of the app running in Spanish. I have photoshopped a couple of screenshots side by side to show different screens of the Note to Self app:
