By replacing MTFlexbox’s deep view hierarchy with Litho’s flattened component tree and moving template parsing to a background thread, Meituan’s app cuts memory usage by over 30 MB, removes FPS spikes on low‑end devices, and improves scrolling performance while preserving custom‑tag and image handling.
Litho is a Facebook‑originated declarative framework for building high‑performance Android UI, replacing XML layouts with component‑based code, leveraging Yoga for async layout, flattening view hierarchies, and offering fine‑grained reuse to dramatically improve RecyclerView scrolling speed and memory consumption.
Litho, Facebook’s declarative Android UI framework, lets developers define components with immutable props and asynchronous layout, flattening view hierarchies and enabling fine‑grained reuse to boost scroll performance and cut memory usage, though it requires custom component code and lacks a real‑time preview.
