Added #

  • Initial release.
  • ConstantDeviceId.getId() — returns a permanent, privacy-safe device identifier.
  • ConstantDeviceId.reset() — clears locally stored ID from Secure Storage and SharedPreferences.
  • Layer 0 — Widevine DRM (Android): hardware-bound ID that survives app uninstall and reinstall. SHA-256 hashed before use.
  • Layer 1 — Secure Storage / iOS Keychain: encrypted storage that persists across reinstalls on iOS.
  • Layer 2 — SharedPreferences: lightweight fallback with automatic promotion to secure storage.
  • Layer 3 — UUID v4 generation: last-resort ID generated once and persisted to both stores.
  • Android minimum SDK: 21 (Android 5.0 Lollipop).
  • iOS minimum version: 12.0.
  • Full unit-test suite with mock platform implementations.
  • Example app demonstrating basic usage.
