Graywater: A Framework for Fast Scroll Performance
summary
A RecyclerView adapter that decomposes large list items into many small view holders via item binders and maps, uses Dagger 2 multibinding to inject binder sets per screen, and keeps layout IDs as view types; the dashboard rewrite takes about a year and the library is under 1,000 lines. It runs on the UI thread only, cannot support nested-post boundaries, and claims practical results — reduced OutOfMemory crashes by ~80% and much less jank compared with the old adapter.
