To implement offline-first architecture, structure your data layer to prioritize local Room entities and synchronize with remote Ktor HttpClient network calls when connectivity restores. This ensures app usability during network interruptions and improves overall data reliability.

Structuring DTOs and mappers in a KMP data layer involves defining plain serializable objects for network transport and writing mapper classes to convert them into domain models. This keeps platform-specific data representation cleanly separated from business logic.

Yes, you can use Ktor HttpClient and Room entities together in a KMP project to handle remote network calls and local persistence. This combination enables a structured offline-first architecture by unifying remote DTOs and local storage within your repositories.

Implement safe API calls and token storage by using safe call helpers to wrap Ktor HttpClient network requests and secure token storage mechanisms for authentication. This provides structured error handling and session management within your data sources.

You should use an offline-first architecture for Android data sources when your app must remain functional during network interruptions. It leverages Room entities for immediate local access and synchronizes with remote APIs when connectivity is restored.
