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.

Android Intents

The Intent class is appropriately named. It is a class that demonstrates the intent of an Activity from our app. It makes intent clear and it also facilitates it.

All our apps so far have had just one Activity, but many Android apps are comprised of more than one.

In perhaps its most common use, an Intent allows us to switch between Activities. But, of course, Activities are classes. So, what happens to the data when we switch between them? Intents handle this problem for us as well by allowing us to pass data between Activities.

Intents aren't just about wiring up the Activities of our app. They also make it possible to interact with other apps, too. For example, we could provide a link in our app for the user to send an email, make a phone call, interact with social media, or open a web page in a browser, and have the email, dialler, web browser, or relevant social media app do all the work.

There aren't enough pages to really dig deep into interacting with other...
