Android Programming for Beginners - Second Edition

By: John Horton

Overview of this book

Are you trying to start a career in programming, but haven't found the right way in? Do you have a great idea for an app, but don't know how to make it a reality? Or maybe you're just frustrated that in order to learn Android, you must know Java. If so, then this book is for you. This new and expanded second edition of Android Programming for Beginners will be your companion to create Android Pie applications from scratch. We will introduce you to all the fundamental concepts of programming in an Android context, from the basics of Java to working with the Android API. All examples use the up-to-date API classes, and 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 and store your user's data with SQLite. In addition, you'll see how to make your apps multilingual, draw to the screen with a finger, 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.

Running the app


You can now run the app and enter a new note, as shown in this next screenshot:

After you have entered several notes of several types, the list (RecyclerView) will look something like this next screenshot:

And, if you click to view one of the notes, it will look like this:

Reader challenge

We could have spent more time formatting the layouts of our two dialog windows. Why not refer to Chapter 5, Beautiful Layouts with CardView and ScrollView, as well as the Material Design website, and do a better job than this. Furthermore, you could enhance the RecyclerView/list of notes by using CardView instead of LinearLayout.

Don't spend too long adding new notes, however, because there is a slight problem: close and restart the app. Uh oh, all the notes are gone!
