Architecture Components The one that got away
summary
A Tinder‑style Star Wars demo implements an offline-first flow using Google Architecture components: UI is a Lifecycle owner that gets a ViewModel; ViewModel exposes LiveData tied to a Room database; repository returns local data immediately, fires a network request, posts the response to a MutableLiveData, writes the network result into Room, and UI updates automatically. Dependency injection holds a singleton Room, JobDispatcher or push handles background sync, and conflicts resolve by timestamp with user actions winning so UI never blocks.
