Modularization for dynamic delivery
summary
Switching to App Bundle and Play’s bundle tool reduces shipped bytes dramatically — Plaid drops about 64% file size savings just by bundling and device-targeted APK splits. Using dynamic feature modules (Lollipop+) enables on-demand downloads, instant (try now) delivery, conditional country/device delivery, and internal app sharing for debuggable installs. Build time falls (clean builds from ~3 min to ~1 min) thanks to parallel module compilation. Play Core handles install requests; runtime checks prevent crashes when modules aren’t present.
