Android Data Layer & Offline-First

Instructions

The Data Layer coordinates data from multiple sources.

1. Repository Pattern

Role: Single Source of Truth (SSOT).

Logic: The repository decides whether to return cached data or fetch fresh data.

Implementation:
class NewsRepository @Inject constructor(
    private val newsDao: NewsDao,
    private val newsApi: NewsApi
) {
    // Expose data from Local DB as the source of truth
    val newsStream: Flow<List<News>> = newsDao.getAllNews()
