This site has been archived and remains strictly as a historical reference for developers who actively maintain apps built using the legacy Google VR SDK, which was last updated in 2019 and is no longer receiving updates.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.

public static final int CARDBOARD

A Cardboard-compatible viewer. A typical Cardboard viewer supports a simple touchscreen-based trigger input mechanism. On most platforms, this is the default viewer type if no viewer has been explicitly paired.

Constant Value: 0

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.
