Build apps for Billions
summary
Moves heavy splash art to the launcher icon and migrated SDKs to background to unblock the main thread, cutting launch time by ~53% and saving 200–500 ms from individual SDKs; replaces JSON reflection with annotated type adapters for a 200–300 ms gain. Network changes — HTTP2 + gzip and omitting null fields — yield ~20–25% faster responses and 75% smaller payloads; images move to WebP and quality bucketing for 25–30% smaller downloads. A central mobile intelligence server with 300 ms TTL collapses 10–15 client calls into one. Build and dev workflow changes give ~40% faster builds and 99.91% crash‑free sessions.
