Making apps blazing fast with Baseline Profiles

on YouTube ↗20m

" summary

Claim: bundling a Baseline Profile cuts startup time (authors report ~30–40% faster) by preselecting methods for AOT so the JIT work is avoided. Generate profiles with Jetpack Macrobenchmark using collectBaselineProfile, save as baselineprof.txt, include androidx.profileinstaller so non‑Play installs apply rules. Baseline Profiles ship in the APK/App Bundle, work back to Android 7, and verify with Macrobenchmark measureRepeated (compare CompilationMode.None vs Partial) or inspect system traces for reduced JIT activity.
