You will also need Android Studio IDE. The examples have been developed using Google's new Android
Studio IDE and use its integrated build system, Gradle. While you can run the examples using the emulator

Specifically for module 3, you will need the latest version of Android Studio and the Android SDK for
Lollipop or newer (API level 22) versions, which you can download using Android Studio.
