Android Performance for Dummies (and Experts)
summary
Conference claims: the SDK behind 8,000+ apps and platform work reaching 100M users; Android Vitals, Android Studio profilers, APK Analyzer, Firebase Crashlytics and Jetpack Benchmark are used to measure and fix issues. Concrete takeaways: 6 MB → 1% install drop, one in four uninstalls is space-related, R8 minify is enabled by default, enable resource shrinking and App Bundles to split APKs, use CPU/GPU traces and GPU overdraw tools, and run Jetpack Benchmark to warm code, stabilize runs and report reliable timings.
