Use Android text like a pro
summary
A feed layout measures at about 4.6 ms where text consumes ~98% of that time; simply disabling hyphenation cuts measurement time roughly in half without visible UI change. Using PrecomputedText moves shaping to a background thread and drops a 4 ms cost to ~0.2 ms (~20× speedup), but native word caches use memory (roughly 20 KB per 500 chars) and PrecomputedText is immutable. Use RecyclerView prefetch with PrecomputedText to precompute text off‑thread and speed up scrolling.
