In 1.0, the ARPointCloudManager managed a single point cloud. Now, it can manage a collection of them, similar to the way other trackable managers work. Some AR platforms, like ARCore and ARKit, still only have a single point cloud. However, other platforms (supported in the future) will generate multiple point clouds.
As a result, the ARPointCloudManager.pointCloud property no longer exists. You can enumerate the point clouds like any other trackable manager, by iterating over its trackables property.
Several APIs used a TryGet or TryAdd style of API. Such methods that dealt with reference types have dropped the Try prefix.
Examples:
1.0
ARPlane.TryGetPlane(trackableId)
ARReferencePoint.TryAddReferencePoint
ARReferencePoint.TryAttachReferencePoint
bool ARReferencePoint.TryRemoveReferencePoint
2.0
ARPlane.GetPlane(trackableId)
ARReferencePoint.AddReferencePoint
ARReferencePoint.AttachReferencePoint
bool
ARReferencePoint.RemoveReferencePoint
The raycasting API is the same as before, only now it is on a new component ARRaycastManager. Previously it was on the ARSessionOrigin. If you need to perform a raycast, make sure you have a ARRaycastManager on the same GameObject as the ARSessionOrigin and use the Raycast methods on that component.
Trackable managers previously had a way to obtain a List of all trackables, e.g., ARPlaneManager.GetAllPlanes and ARReferencePointManager.GetAllReferencePoints. There is now a common property called trackables, which can be used in a foreach, e.g.:
var planeManager = GetComponent();
foreach (var plane in planeManager.trackables) {
// Do something with the plane
}
This property returns a TrackablesCollection which does not generate any garbage or cause boxing.
The ARSubsystemManager has been removed in 2.0. It was previously a singleton which provided access to each of the "subsystems" (the low-level interface to the AR platform). However, some subsystems were also simultaneously managed by a MonoBehavior, e.g., ARPlaneManager.
The led to confusion about which object to interact with or subscribe to. Now, each "subsystem" has a manager component which not only provides access to that subsystem, but also manages its lifetime.
If you previously used the ARSubsystemManager, look for similar functionality on one of the managers:
The ARCameraManager enables the XRCameraSubsystem; without it, you will not be able to use background rendering or obtain light estimation information. This component should be placed on a Unity Camera, usually on the same one that is parented to the ARSessionOrigin and performs background rendering.
The ARCameraBackground now requires an ARCameraManager component.
The options that were previously on the ARCameraOptions component, like focus mode and light estimation mode, are now on the ARCameraManager. The ARCameraOptions no longer exists.
Sau khi tạo một cảnh trống, chuyển sang nền tảng android, cấp API min = Android 7(24) và nhập :
ARFoundation 1.5.0-xem trước.7
ARCore XR Plugin 2.1.2
Khi build lên thì xuất hiện các lỗi sau :

TL;DR
Add an ARInputManager anywhere in your scene.
Add an ARCameraManager to your AR camera (this replaces the ARCameraOptions).
Raycast via the ARRaycastManager instead of the ARSessionOrigin
Some TryGet/TryAdd/TryRemove APIs were renamed to just Get/Add/Remove
GetAllXXX is now a trackables property
Added, update, and removed events have been combined into a single event that gives you lists of all the added, updated, and removed trackables.
Events
In 1.0, each trackable manager provided added, updated, and removed events for each trackable. In 2.0, each trackable manager has a single event invoked no more than once per frame containing all the changes (added, updated, and removed) since the last frame.
Example:
1.0
ARPlaneManager.planeAdded, ARPlaneManager.planeUpdated, ARPlaneManager.planeRemoved
2.0
ARPlaneManager.planesChanged
Many of the trackables in AR Foundation 1.0 had "session relative data", e.g., BoundedPlane and XRReferencePoint. These are no longer directly accessible; all their memebers are now properties of an AR Foundation trackable.
Example:
Trackable:ARPlane
1.0 accessor:boundedPlane.Id
2.0 accessor:trackableId
Previously, pose tracking was implicitly always on. Now, you must have an ARInputManager component in your scene to enable it. It does not matter what GameObject this is on.
The ARInputManager enables input tracking; the TrackedPoseDriver consumes pose data (as before).
