  • There's a new open source Cardboard SDK for iOS and Android NDK that offers a streamlined API, improved device compatibility, and built-in viewer profile QR code scanning. A corresponding Unity package (SDK) is planned for a future release. We recommend that all developers actively building for Google Cardboard migrate (iOS, Android NDK) to the new Cardboard SDK.
