Deep dive into Modern Android Performance
summary
Shows concrete wins and tools: customers cut cold start ~30% (Zomato → +90% day‑one retention, +600k orders; Google Maps → +30% start, +2.4% searches) and reduced ANR/jank (>50% reduction at OkayCredit → +20% retention, +30% transactions). Recommends Baseline Profiles (local generation via instrumentation yields ~21% faster startup in example), measuring with Jetpack Macrobenchmark and system traces, monitoring with Android Vitals and Firebase Perf, generating profiles on a rooted device or with Gradle managed devices, and tracking jank with JankStats.
