Android Programming for Beginners - Third Edition

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 the app

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

After you have entered several notes of several types, the list (RecyclerView) will look something 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 we have done so far? Furthermore, you could enhance the RecyclerView class/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!
