ARCore SDK for Android v1.34.0

New APIs and capabilities

Check Geospatial VPS availability

A new ARCore Geospatial API has been added to check for Visual Positioning System (VPS) availability at a specified horizontal position at runtime. This API can be used without an active AR session, for example, to present an "Enter AR" button only when VPS is available.

• Kotlin/Java
  • Developer guide: Check VPS Availability
  • Session.checkVpsAvailabilityAsync()
• C
  • Developer guide: Check VPS Availability
  • ArSession_checkVpsAvailabilityAsync() determines if VPS is available in a given area. This will initiate a query with a remote ARCore API service.

Geospatial pose orientation

Geospatial poses now expose their orientation in 3D space.

• Kotlin/Java reference
  • GeospatialPose.getEastUpSouthQuaternion()
• C reference
  • ArEarth_getGeospatialPose()

Geospatial pose conversions

Geospatial poses can now be converted to and from world-space poses.

• Kotlin/Java reference

  • Earth.getGeospatialPose() converts a Pose to a GeospatialPose in the same position.
  • Earth.getPose() converts a geospatial location and orientation to a Pose in the same position.

• C reference

  • ArEarth_getGeospatialPose() converts the input pose to a ArGeospatialPose in the same position.
  • ArEarth_getPose() converts a geospatial location and orientation to an ArPose in the same position.

Note that Geospatial poses obtained from these functions have a heading value set to zero. Instead, use its EUS quaternion instead.

Other changes

• The geospatial_java sample has been adjusted to check for VPS availability.
• The geospatial_java sample now supports creating a Geospatial anchor by tapping on the AR camera view.
• Updated Kotlin samples to Kotlin version 1.5.30 from 1.4.20.

Bug fixes

• Fixed "Device Not Supported" being reported for emulator images on ARM host machines.
• ArEarth_getEarthState() and ArAnchor_getTerrainAnchorState() now correctly return ERROR_NOT_AUTHORIZED when there is an authentication issue instead of returning ERROR_INTERNAL.
