Endigest AI Core Summary
Pinterest's approach to automatically measuring user-perceived latency (Visually Complete) on Android surfaces by embedding measurement logic into base UI classes.
•User-perceived latency is crucial for mobile app performance, but defining Visually Complete varies by surface (e.g., video playback vs. image rendering)
•Implementing custom measurement logic for each surface required approximately two engineer-weeks per surface, creating a barrier for product engineers
•Solution: Built Visually Complete logic into BaseSurface class with common media view interfaces (PerfImageView, PerfTextView, PerfVideoView)
•System iterates through the view tree to check rendering status of all visible UI elements, automatically measuring latency for any new surfaces
•
Currently monitoring over 60 surfaces in production on Android, with extension to iOS and web platforms
