Getting Started

Welcome to Training for Android developers. Here you'll find training classes that describe how to accomplish a specific task with code samples you can re-use in your app. Classes are organized into several groups you can see at the top-level of the left navigation.

The first training guides below teach you the essentials for Android app development. If you're a new Android app developer, you should complete each of these classes in order.

Various online video courses are also available if you'd prefer an interactive video experience.
