It’s a Wrap!
We’ve just finished the first series in the MAD Skills series of videos and articles on Modern Android Development. This time, the topic was Navigation component, the API and tool that helps you create and edit navigation paths through your application.
The great thing about videos and articles is that, unlike performance art, they tend to stick around for later enjoyment. So if you haven’t had a chance to see these yet, check out the links below to see what we covered. Except for the Q&A episode at the end, each episode has essentially identical content in the video and article version, so use whichever format you prefer for content consumption.
Episode 1: Overview
The first episode provides a quick, high-level overview of Navigation Component, including how to create a new application with navigation capability (using Android Studio’s handy application templates), details on the containment hierarchy of a navigation-enabled UI, and an explanation of some of the major APIs and pieces involved in making Navigation Component work.
Episode 2: Dialog Destinations
Episode 2 explores how to use the API to navigate to dialog destinations. Most navigation takes place between different fragment destinations, which are swapped out inside of the
NavHostFragment object in the UI. But it is also possible to navigate to external destinations, including dialogs, which exist outside of the
Episode 3: SafeArgs
This episode covers SafeArgs, the facility provided by Navigation component for easily passing data between destinations.

Episode 4: Deep Links
This episode is on Deep Links, the facility provided by Navigation component for helping the user get to deeper parts of your application from UI outside the application.

Episode 5: Live Q&A
Finally, to wrap up the series (as we plan to do for future series), I hosted a Q&A session with Ian Lake. Ian fielded questions from you on Twitter and YouTube, and we discussed everything from feature requests like multiple backstacks (spoiler: it’s in the works!) to Navigation support for Jetpack Compose (spoiler: the first version of this was just released!) to other questions people had about navigation, fragments, Up-vs-Back, saving state, and other topics. It was pretty fun — more like a podcast with cameras than a Q&A.

Sample App: DonutTracker
The application used for most of the episodes above is DonutTracker, an app that you can use for tracking important data about donuts you enjoy (or don’t). Or you can just use it for checking out the implementation details of these Navigation features; your choice.
