v1.120.0

Behavioral changes

• Recentering API now supports 3 degree-of-freedom head tracking:
  • GVR_EVENT_RECENTER events (whose data type is
    gvr_recenter_event_data) are queued when recentering occurs.
  • GVR_PROPERTY_RECENTER_TRANSFORM property returns the current start
    space from sensor space transform.

Other changes

• DaydreamApi.setVrContentIntent function added for marking notifications as
  safe to launch in VR.
• New Video360 sample. This uses the base GVR SDK and shows how to create a
  360 image & video viewer similar to VrView. It has a 2D Activity built using
  standard Android & OpenGL APIs and a VR Activity built on the Daydream APIs.
  See https://developers.google.com/vr/android/samples/video360 for more info.
• HeadMountedDisplayManager is deprecated and no longer part of the public
  SDK. Headset parameters can be obtained via
  GvrView#getHeadMountedDisplay().
• Java wrappers for the native event APIs have been added to the NDK. See also
  GvrApi#pollEvent(Event).
• The Java wrapper for ExternalSurface has been removed from the public
  NDK, as this class is not directly usable with the current set of APIs.
