In the past year, Facebook for Android has moved from a primarily webview based app to an almost entirely native experience. It has transitioned from being built by a small team to a distributed development model where product teams are responsible for their features. And it has grown to be used by well over a hundred million users a day, distributed across devices with orders of magnitude differences in capabilities.

This talk describes the technical and cultural challenges associated with making these transitions while continuing to ship a fast and lightweight app. In particular, we will focus on:

  • changes we made to the process of building and releasing our apps to make sure we only shipped the bits that matter to each user.
  • an analytics framework that lets us measure and optimize various performance metrics, and make the costs of features visible to product teams.
  • core libraries and abstractions that make it easier to distribute development without hurting overall performance of the app.

The talk will draw on real examples from a broad set of performance metrics such as startup time, data usage, disk usage, app size, battery consumption etc.

Hi Chaitanya, I loved your presentation. It was nice to see the Facebook approach on the Android app. Is there a URL where I can download the presentation? Thank you.
