Composed for Success: Automatic Instrumentation in Jetpack Compose
summary
Automatic instrumentation for Jetpack Compose that generates navigation and UI-interaction breadcrumbs without touching app code, using lifecycle observers + DisposableEffect for navigation, window.dispatchTouchEvent + GestureDetector for clicks, view-hierarchy traversal for Views and direct access to Compose semantics via the UI node tree for Compose targets. A Kotlin compiler plugin injects modifiers and a Gradle bytecode manipulation step adds hooks so apps see breadcrumbs out of the box; internal-API workarounds are used and basic tracing already works.
