Content

Use the content module to discover, download, manage, and update offline packages such as maps, view styles, and voice packs. This system helps you build reliable offline workflows for navigation, rendering, and voice guidance by exposing discovery, lifecycle, and update primitives for packaged content.

  • ContentStore: Use this central manager to discover available catalogs, inspect local availability, and orchestrate lifecycle actions like downloads and removals. It tracks overall content state and coordinates other content-related operations.
  • ContentStoreItem: Use this model to represent a single downloadable product (map region, style package, or voice pack). Items carry identity, availability metadata, download status, and preview information that your app manipulates when presenting or managing offline content.
  • ContentUpdater: Use this coordinator to perform and monitor updates for a specific content type. It handles update orchestration, progress reporting, readiness checks, and supports canceling or resuming update flows as needed.

These components work together to provide a robust content lifecycle: ContentStore discovers and exposes items, ContentStoreItem models the individual packages you act on, and ContentUpdater executes the actual update operations. Together they enable reliable offline experiences with clear progress, resumability, and consistent state management.

For typical usage, query ContentStore to list available items and inspect local availability via ContentStoreItem. When updates are required, use ContentUpdater to start and monitor operations, and prefer resumable flows and clear cancellation semantics for better user experience.
