    Just following the instructions from the google developers website to get ARCore running in Unity leads to this console error:
    Assets/GoogleARCore/SDK/InstantPreview/Scripts/InstantPreviewManager.cs(32,23): error CS0234: The type or namespace name `SpatialTracking' does not exist in the namespace `UnityEngine'. Are you missing an assembly reference?

    And furthermore I have: Assets/GoogleARCore/Examples/CloudAnchor/Scripts/ARKitHelper.cs(50,71): error CS0246: The type or namespace name `Pose' could not be found. Are you missing an assembly reference?

    I couldn't find anything online relating to this error, and would appreciate any help.

    Thanks

    May I know which Unity version you are using to solve this issue?

    I still have this problem on Unity 2019.1.3f1

    TrackedPoseDriver.cs exists in my project.

    it reads
    Code (CSharp):
    1. [assembly: InternalsVisibleTo("UnityEditor.SpatialTracking")]
    then below
    Code (CSharp):
    1. namespace UnityEngine.SpatialTracking
    could this be a mismatch?

    I just ran into this issue during package maintenance:

    As Chaosemer points out, the solution is clearly stated on the ARCore website. (Which ideally should be split by Unity version given that each version has its required tweaks)

    Download the ARCore SDK for Unity and import it into your project by clicking the menu Assets > Import package > Custom Package. (Unity 2019 only: To fix the compilation errors, use Window > Package Manager to install the Multiplayer HLAPI and XR Legacy Input Helpers packages.)

    Crazy behavior noted: When I moved my project from 2019.1.14f1 on MAC to 2019.1.14f1 on Windows, it gave me this error. But when I built the project on Windows using 2018.3.7f1, it worked absolutely fine. No idea how and why.

    For people using Unity 2020 versions:
    Multiplayer HLAPI and XR Legacy Input Helpers packages are hidden in this Unity 2020 versions

    Here’s the easiest way to regain access to those missing packages:
    • Go to Window -> Package Manager
    • Click the drop-down menu (plus icon) on the top left of the window, and select add package from git URL
    Type the following urls to add those packages:
    com.unity.multiplayer-hlapi
    com.unity.xr.legacyinputhelpers
