Architecture Components – Behind the Scenes
summary
Architecture Components (released at I/O’17) claims to make Android fundamentals easier by shipping concrete libraries: an observable lifecycle API that works back to API 14, a Room persistence layer that lets developers write SQL with compile‑time verification and migration support, and LiveData plus ViewModel + Repository guidance to avoid god objects. Room forbids main‑thread queries and rejects implicit nested entity relations; early access previews reach alpha4 and the team iterates with community feedback and sample apps.
