XRObjectTrackingFeature
This OpenXRInteractionFeature configures Android XR extensions XR_ANDROID_trackables and XR_ANDROID_trackables_object at runtime and provides XRObjectTrackingSubsystem implementation that works on Android XR platform.
Note: due to the dependency on XRSessionFeature, its priority must be lower than it so the feature registration happens after XrInstanceManager creation.

Public attributes
ExtensionStrings
const string ExtensionStrings =
"XR_ANDROID_trackables " +
"XR_ANDROID_trackables_object"
The OpenXR Extension string.
Used to check if this extensions is available or enabled. To enable runtime confiugration, always enabling persistence extension when it's available.
FeatureId
const string FeatureId = "com.google.xr.extensions.object_tracking"
UiName
const string UiName = "Android XR (Extensions): Object Tracking"
The UI name shows on the XR Plug-in Management panel, help users to understand validation errors and expected fixes.
Public static attributes
IsExtensionEnabled
bool IsExtensionEnabled => _extensionEnabled
Gets if the required OpenXR extension is enabled.
When OpenXR runtime is waiting, it returns null. Otherwise, it indicates whether the XR_ANDROID_trackables and XR_ANDROID_trackables_object extensions are available on current device.
RequiredPermission
readonly AndroidXRPermission RequiredPermission =
AndroidXRPermission.SceneUnderstandingCoarse
Runtime permission required to enable scene understanding.
