summary

Migrating a large banking app moves incrementally: a bottom-up approach replaces inner widgets first, using ComposeView, androidView composable and ComponentActivity.setContent to interoperate with existing XML. The team migrates a core theming library (Euphemia) and a common-ui layer (Tetris), proves a three‑composable POC, and solves AGP/Kotlin/Activity version conflicts (AGP 7+, Kotlin ~1.5.21, Activity 1.3+, Compose 1.0.1). Tests need rework (Espresso vs compose test rules), migration is iterative and working but not yet complete. bottom-up approach
