ARCH Components

" summary

Google's Android Architecture Components are used: ViewModel survives config changes and includes an onCleared hook to dispose resources; LiveData only notifies active observers with setValue (main thread) vs postValue (background), and observeForever must be removed to avoid leaks; Room validates SQL at compile time (entities, DAOs, database) and integrates with LiveData. Implementation claim: simple, low overhead (~600–700 methods across libs), covers ~80–90% of app use cases, and noticeably reduces lifecycle boilerplate.
