Win on startup time! Improving app launch performance
summary
Shows how to measure Android cold start with Macrobenchmark (10 iterations) to capture TTI, then add reportFullyDrawn to get TTFD and use Android Studio CPU profiler to find OnCreate bottlenecks. Recommends replacing auto-added content providers with the App Startup library, generating baseline and launch profiles embedded in the APK, and using Firebase Performance Monitoring; combining baseline+launch profile tuning gives roughly 10–20% startup improvements while profiler-driven fixes find the biggest wins.
