When you notice FPS glitches in your app, how do you find and fix them? This talk will discuss various options for measuring FPS, and some of the work Facebook’s Android Newsfeed team is doing to improve interaction smoothness. This includes some of the automated solutions Facebook uses to blame janky frames both in the wild and in automated tests.
I've been working on the Facebook for Android app for the past 5 years. In that time, I've worked on scroll performance for News Feed and rewritten the rendering infrastructure for News Feed twice. I'm a Litho wizard, a scroll performance guru, and I am sometimes lucky enough to stumble my way through Flexbox.
