Assembling your Jetpack
summary
Integrating Jetpack into an existing app is shown end to end: a Kotlin MVVM sample called Sunflower (open on GitHub) implements a working gardening app with about a dozen plants, a Room-backed database, LiveData-observed queries and DataBinding-updated UI, coroutine usage and a single-activity/many-fragments navigation pattern. The talk demonstrates database DAOs, view models preserving state, safe-args navigation and compile-time checks, and migration paths with AndroidX migration tool and CSV mappings, plus the core libraries Room, LiveData, ViewModel, DataBinding, Navigation, and the open sample Sunflower on GitHub.
