Actionable App Performance Measurement
summary
Practical recipe for faster apps: upgrade to AGP8, enable R8 and ship baseline profiles plus startup profiles; macrobenchmark generates profiles and measures startup/frame metrics, Peretto or Android Studio trace viewer profiles hotspots. Claims backed by numbers: startup profiles speed startup ~30%, baseline+startup reach ~50–60% on first run, R8 speeds runtime up to ~30%. Baseline profiles are reproducible (a 30-minute workshop with ~40 participants produced profiles for about half the apps). Also describes an interactive on-device scoring test and an App Performance Score to track progress.
