Android On-Demand

In 2016, Google announced Instant Apps, quickly followed in 2018 by Dynamic features for Android. Over the last two years, Google has put a lot of effort toward modularizing Android applications in order to enable on-demand features in our devices. This talk will focus on my personal experiences migrating a monolith into an instant dynamic Android app at Chewy.

Chewy is among the first companies to debut Instant Dynamic Apps in the Play Store. During the process, we've encountered many things that will prove valuable to others attempting to achieve the same goal.
