UpdateInfoManager

public final class UpdateInfoManager

Manages the persistent storage of security update information.

This class acts as the local database for the UpdateInfoService. It is responsible for:

1. Storing the list of available UpdateInfo objects (persisted in SharedPreferences).

2. Storing metadata about the update checks (e.g., getLastCheckTimeMillis).

3. Cleaning up outdated updates by comparing them against the device's current state.

Typical usage involves an update client (like GOTA (Google Over-The-Air) or Play Store) registering new updates via registerUpdate when they are discovered, and the UpdateInfoService querying getAllUpdates to return them to consumers.
