ARCore SDK for Android v1.23.0

Breaking & behavioral changes

• AR-enabled apps built using ARCore SDK 1.11.0 or earlier are no longer able to host or resolve Cloud Anchors.
  • C: Cloud Anchors returned by ArSession_hostAndAcquireNewCloudAnchor and ArSession_resolveAndAcquireNewCloudAnchor will always have the state AR_CLOUD_ANCHOR_STATE_ERROR_INTERNAL.
  • Java: Cloud Anchors returned by Session#hostCloudAnchor(Anchor) and Session#resolveCloudAnchor(java.lang.String) will always have the state Anchor.CloudAnchorState.ERROR_INTERNAL.
  • Apps built with ARCore SDK 1.12.0 or later are unaffected. Their use of Cloud Anchors APIs is covered by the deprecation policy.

New APIs and capabilities

• Developers can enable ARCore API call logging to the Android debug log by sending a broadcast intent.
• Developers can enable the ARCore performance overlay by sending a broadcast intent.
• Added new API for switching between rear-facing (world) and front-facing (selfie) camera configs within the current Session.
  • Java: Developer guide, CameraConfigFilter.getFacingDirection(), CameraConfigFilter.setFacingDirection().
  • C: Developer guide, ArCameraConfigFilter_getFacingDirection() ArCameraConfigFilter_setFacingDirection().

Deprecations

• The following session features are being deprecated:
  • Java: Feature FRONT_CAMERA is deprecated. To create a session using the front-facing (selfie) camera, use Session.setCameraConfig(CameraConfig) to set a front-facing(selfie) camera config retrieved from Session.getSupportedCameraConfigs(CameraConfigFilter).
  • C: Feature AR_SESSION_FEATURE_FRONT_CAMERA is deprecated. To create a session using the front-facing (selfie) camera, use ArSession_setCameraConfig to set a front-facing(selfie) camera config retrieved from ArSession_getSupportedCameraConfigsWithFilter.

Deletions

• The following deprecated APIs have been deleted:
  • ArImageMetadata_getNdkCameraMetadata
  • ArImage_getNdkImage

Other changes

• Java: Updated hello_ar_java to use the cubemaps provided by Environmental HDR Lighting Estimation for specular reflections.
• Updated augmented_faces_java sample app to use the new ArCameraConfigFilter_setFacingDirection() API to create a session using the front-facing (selfie) camera instead of using the FRONT_CAMERA Session feature, which has been deprecated.
• Updated computer_vision_c sample app to use functions of 'ArImage' instead of functions of AImage to obtain image data, to avoid using previously deprecated ArImage_getNdkImage.

Bug fixes

• Various bug fixes and performance improvements.
