Perfetto Your App for Perfect Performance
summary
Perfetto is a browser-based systemwide tracer that records CPU, threads, wake locks and UI events and shows jank when a frame exceeds 16.6 ms; traces come from ADB, Android Studio or a quick‑settings button and require adding a profilable flag to production builds for deeper data. The workflow is: record, inspect thread states and bounded transactions, add custom trace markers via Trace APIs or AndroidX Tracing KTX, instrument coroutines with a custom dispatcher, hook Looper.setMessageLogging and OkHttp or RxJava schedulers, then re-record to verify fixes.
