Something old, something new: Adding Jetpack Compose to a large open source Android app

on YouTube ↗35m

" summary

Takes Jetpack Compose into the large open‑source Habitica Android app and reports concrete results: repo shows 26 activities, 33 fragments, 12 repositories, 7 view models, 13 view holders; interop uses ComposeView in XML and composables inside RecyclerView view holders; theme conversion fails to capture 27 custom colors and 82 styles so a composition local approach stores extended colors; builds an About screen and a to‑do card that animates with one line of code, but app tests are all red so no PR is merged.
