Start building native Android apps the modern way in Kotlin with
Jetpack's expansive set of tools, libraries, and best practices. Learn
how to create efficient, resilient views with Fragments and share data
between the views with ViewModels. Use Room to persist valuable data
quickly, and avoid NullPointerExceptions and Java's verbose expressions
with Kotlin. You can even handle asynchronous web service calls
elegantly with Kotlin coroutines. Achieve all of this and much more
while building two full-featured apps, following detailed, step-by-step
instructions. With Kotlin and Jetpack, Android development is now
smoother and more enjoyable than ever before. Dive right in by
developing two complete Android apps.
With the first app, Penny Drop, you create a full game complete with
random die rolls, customizable rules, and AI opponents. Build
lightweight Fragment views with data binding, quickly and safely update
data with ViewModel classes, and handle all app navigation in a single
location. Use Kotlin with Android-specific Kotlin extensions to
efficiently write null-safe code without all the normal boilerplate
required for pre-Jetpack + Kotlin apps. Persist and retrieve data as
full objects with the Room library, then display that data with
ViewModels and list records in a RecyclerView.
Next, you create the official app for the Android Baseball League. It's
a fake league but a real app, where you use what you learn in Penny Drop
and build up from there. Navigate all over the app via a Navigation
Drawer, including specific locations via Android App Links. Handle
asynchronous and web service calls with Kotlin Coroutines, display that
data smoothly with the Paging library, and send notifications to a
user's phone from your app.

What You Need:
You'll need the Android SDK, a text editor, and either a real Android
device or emulator for testing. While not strictly required, it's
assumed you're using Android Studio, which comes with the Android SDK
and simplifies creating an emulator. Also, a few examples require JDK
1.8 or later, though all of these pieces can be completed in other ways
when using JDK 1.6.
