November 6, 2019 update:
  • There's a new open source Cardboard SDK that offers a streamlined API, improved device compatibility, and built-in viewer profile QR code scanning. We recommend that all developers actively building for Google Cardboard migrate to the new Cardboard SDK: iOS, Android NDK, Unity XR Plugin (SDK)
October 15, 2019 update:
  • The Daydream View VR headset is no longer available for purchase. However, you can continue to use the existing Google VR SDK to update and distribute your apps to the Google Play Store, and make them available to users in the Daydream app.

public static final int DAYDREAM

A Daydream-compatible viewer. A typical Daydream viewer supports 3DoF controller input (as defined in gvr_controller.h), and is intended only for Daydream-ready platforms. It does *not* support touchscreen-based input unless Cardboard emulation is explicitly enabled.
