Announcing Android Apprentice, Fourth Edition!

The Android Apprentice book is your best resource for building great apps, using Kotlin. Now updated for Android 11, Kotlin 1.4 and Android Studio 4.1!

If you’ve started down the path of learning Android development, have you ever had the sinking feeling that “there’s so much to learn — where on earth do I start?”

You’re not alone! Whether you’re getting into Android to build a nice portfolio of apps for your next job search, or to build your reputation in the open-source community, or even just for the fun of it, you want to get up to speed in the least amount of time possible. On top of that, because the Android world moves so fast, you need to be sure that you’re not learning old information that will lead you astray.

How to Get Started Building Android Apps

First, it feels like there are a lot of things you need to know to build robust, beautiful apps:

  • Basic concepts like Layouts, Activities, debugging and networking
  • Persisting user data and communicating between Activities & Fragments
  • Building out your UI and adhering to Material Design principles
  • Manging more advanced elements, like mapping and media playback
  • …and then there’s the whole app release cycle as well!

Finding the right resources, as well as ones that are up-to-date, can be challenging.

But we’ve got just the right book, with just the right sample apps, to help you level up as an Android developer as you build out your first real-world Android apps: Android Apprentice!

How Can This Book Help?

This book is your introduction to building great apps for Android, using the Kotlin language. Whether you consider yourself a novice programmer, or have experience programming on other platforms, this is the book for you!

It’s not our aim to teach you all the ins and outs of Android development, or teach you the entire Kotlin language. They are huge concepts on their own, and there’s no way we can cover everything.

Instead, this book helps you master the essential strategies you need to build great Android apps using Kotlin. You’ll be able to take the core lessons from this book and bring them forward into your future apps, where you’ll be able to apply them to more complicated app scenarios you encounter.

The most important thing you’ll learn is how to think like a programmer. This will help you approach any programming task with confidence, whether it’s a game, a utility, a mobile app that uses web services, or anything else you can imagine.

Updated for Android 11

We know it’s frustrating to find Android development resources or courses on the internet, only to realize too late that it’s several years old, and that the concepts just don’t apply anymore.

That’s why we’ve completely updated the Fourth Edition of this book, from top to bottom, for the latest and greatest versions of everything:

  • Updated for Android 11, Android Studio 4.1, and Kotlin 1.4
  • Updated for 2021 Google Play Store processes
  • Updated all sample apps for modern design patterns and for best practices such as databinding!

What’s Inside the Book?

Android Apprentice has everything you need to know about building your first Android app, all the way to publishing it for sale, in a whopping 31 chapters divided into six sections:

  • Section I – Your First Android App: This is your introduction to creating apps in Android. This section will take you step-by-step through installing Android Studio and working inside the IDE and visual designer while you build Timefighter, a simple game that uses many common Android components.
  • You’ll start with the fundamentals, before moving on to more complex concepts.

  • Section II – Building a List App: In this section, you’re going to create your own project from scratch! You’ll also learn how to persist data to your app using SharedPreferences and create different screens dedicated to different tasks. Towards the end of the section, you’ll learn how to change your app to adapt to different screen sizes using Fragments, and how to enhance your apps to follow Material Design principles.
  • Learn how to work with Material Design best practices to bring your apps to life!

  • Section III – Creating Map-Based Apps: In this section, you’ll build PlaceBook, a location based app that lets you bookmark your favorite places and save some notes about each place. This section introduces several new concepts including Google Maps, Room database, drawer navigation, and camera control.
  • Build map-based apps that your users will find useful *and* beautiful!

  • Section IV – Building a Podcast Manager & Player: This section gets a bit more advanced. You’re going to build a podcast manager and player app named PodPlay. You’ll cover networking, notifications, working with REST and XML, and the Android media libraries.
  • Build a fully-featured podcast and videocast player of your own!

  • Section V – Android Compatibility: This section covers two Android topics that are almost as important as your Android app itself: how to handle the collection of Android versions out there, known as the fragmentation problem, and how to best keep your app up to date in the face of constant updates to Android.
  • Android moves fast as a platform – learn how to stay on top of fragmentation issues!

  • Section VI – Publishing Your App: Now that you’ve created your app, you need to get it out to the world! This section has two chapters that teach you how to prepare your app for release, how to test your app, and how to publish your app to your waiting fans!
