This site has been archived and remains strictly as a historical reference for developers who actively maintain apps built using the legacy Google VR SDK, which was last updated in 2019 and is no longer receiving updates.
  • All developers actively developing experiences for Google Cardboard should use the new open source Cardboard SDKs for iOS, Android NDK, and Unity XR Plugin. These new SDKs offer streamlined APIs, improved device compatibility, and built-in viewer profile QR code scanning.
  • The Daydream View VR headset is no longer available for purchase as of October 15, 2019. Existing apps on supported devices are unaffected for users who previously installed those applications. It is no longer possible to opt-in to Daydream distribution via Google Play.
