The Confidence Android SDK provides feature flag evaluation for Android applications. Flags resolve once according to the evaluation context, and values read from a local cache for fast access.

​
Features

  • Local caching: Flag values cached locally for instant access
  • OpenFeature compatible: Standard feature flag API through OpenFeature provider
  • Automatic apply events: Tracks flag usage
  • Managed context: Automatic visitor ID and app lifecycle context
  • Offline support: Cached values available without network
