" summary

Uses Android Studio CPU profiler to find an 800 ms main‑thread blocker (loadAndParseBootstrapData) and proves preloading on a background thread removes the jank; uses tracing profiler and systrace to show missed frames on a Pixel 3 and that a stray thread.sleep plus a duplicated data binding call cost real frames; shows executePendingBindings double bind 30% wasted work; demonstrates Jetpack Benchmarking library behavior, its need for rooted device and repeatable fake numbers, and compares coroutines vs executor overhead.
