Turbo Charging Your Android Notifications

Android notifications are a great way to keep your users engaged with your app. And now with Android 5.0 (Lollipop) notifications are front and center on the Android platform, which means it’s even more important for you as a developer to learn how to take advantage of this very powerful Android feature.

In this class, we will take a technical deep dive into Android notifications. You will learn how to add notifications to your app, how to customize notifications to better display the information you need to present and how to take advantage of advanced features like inbox style notifications, custom layouts and custom actions. We will also explore other important aspects of Android notifications, like compatibility with previous version of Android and the possibility to extend your app’s notifications into Android Wear devices.
