Multi-threaded rendering on Android (with Litho & Infer)

The Facebook UI Foundation team develops UI rendering infrastructure for common surfaces in the Facebook app. We recently migrated the Facebook Android News Feed codebase to background rendering in a scalable, safe, and performant manner. This talk will introduce how our teams completed this migration utilizing two open source libraries – Litho, a declarative UI Framework, and Infer, an analyzer which automatically finds concurrency bugs (and other bugs too!). We’ll share some of the issues we ran into, performance results, and how you too can use these libraries in your own app.
