About This Article
ShareChat's RecyclerView was creating too many viewholders and making redundant requestLayout calls during bind operations. This slowed down the app for their 180M+ monthly active users.
ShareChat built a Shared RecyclerView Pool to reduce viewholder creation costs. They also refactored the code to capture values when viewholders were created instead of on every bind, which stopped unnecessary layout recalculations.
Janky frame rates per 10K frames dropped from 10.72% to 3.98%. Their Play Store rating went from 4.0 to 4.3 stars.
