The Light Way

droidcon NYC 2019 | The Light Way | Lisa Wray

What if an app could be performant by being simple? What if an app could work “at scale” for 1 billion users using only standard Android paradigms? At Facebook, we support some of the biggest, most complex apps in the world, but we also support developing countries, low-memory phones, and spotty networks. So, in Messenger Lite, we tried something different. We prioritized cold start and APK size by going back to basics. We limit our dependencies and our feature set, and we embrace what the Android framework provides to make a completely native app that’s featherweight and really, really fast. Lisa Wray will walk you through how these tools, like data binding, RecyclerViews, a database-driven UI, and simply writing less code, are available to every Android developer who wants to build their app the lite way.
