ARCore Extensions for AR Foundation v1.28.0

Known issues

• None

Breaking & behavioral changes

• Beginning in November 2022, AR-enabled apps will no longer be able to acquire NDK images or image metadata. The SDK versions impacted depend on the specific function being called, see the deprecation announcement to learn more.
  • C: Calls to ArImage_getNdkImage and ArImage_getNdkCameraMetadata will always return nullptr for the AImage and ACameraMetadata objects.
  • Java: The Image object returned by Frame#acquireCameraImage() will be of size 0x0 pixels. Calls to Frame#getImageMetadata() will always throw IllegalArgumentException.
  • Unity (AR Foundation):
    • When using AR Foundation 2.1 (Unity 2019 LTS), calls to XRCameraSubsystem.TryGetLatestImage(out XRCameraImage) will always return false.
    • AR Foundation 4.x and later versions are unaffected, calls to XRCameraSubsystem.TryGetLatestImage(out XRCameraImage) will behave normally.
  • ARCore SDK for Unity (deprecated): Calls to Frame.CameraImage.AcquireCameraImageBytes() will be of size 0x0 pixels. Calls to Frame.CameraMetadata.GetAllCameraMetadataTags() will return an empty List<CameraMetadataTag>.

Other changes

• To support Android 12, ARCore Extensions for AR Foundation now requires Gradle version 6.1.1 or later and Android Gradle Plugin 4.0.1 or later. For details, refer to Building for Android 12.
• Removed CloudAnchors sample since the Unity HLAPI package is no longer available in Unity 2021.2 and later. The PersistentCloudAnchors sample remains and should be used instead.
• The ARCore Extensions SDK now only automatically cleans up External Dependency Manager dependencies in batch mode to avoid conflicts when patching Assets/Plugins/Android/mainTemplate.gradle, for example when building for Android 11 or Android 12.

Bug fixes

• Fixed issue where ARCoreExtensionsCameraConfigFilter fails to render its field labels in Unity 2020.3.
