Unity Cardboard XR Package Fails Initialization - logcat reveals a missing DLL error

[Leli1024]

Hi,

So I'm using Unity 2022.2.0f1 and I'm using the latest version of the Cardboard XR Plugin and the code fails at the following line, I've tried everything including targeting different architectures

        Debug.Log("Initializing XR...");
        yield return XRGeneralSettings.Instance.Manager.InitializeLoader(); //Line where it's failing

        if (XRGeneralSettings.Instance.Manager.activeLoader == null)
        {
            Debug.LogError("Initializing XR Failed."); //If statement leads to here
        }
        else
        {
            Debug.Log("XR initialized.");

            Debug.Log("Starting XR...");
            XRGeneralSettings.Instance.Manager.StartSubsystems();
            Debug.Log("XR started.");

            SceneManager.LoadScene("RandomGame");
        }
        Debug.Log(XRGeneralSettings.Instance);
        Debug.Log(XRGeneralSettings.Instance.Manager);

Furthermore I get the following error on Logcat. I've tried to include the GFX aar file via the link.xml file however this did not work

Thanks for reporting this issue.
After closer inspection I’ve noticed that you reported that this is happening on Unity 2022.2.0f1 which is not an LTS version of Unity.

Are you able to reproduce this issue on Unity 2022.3.45f1?

Hi @Leli1024,

Have you checked if the Cardboard XR plugin is selectable in the XR Plugin-in Management section of the Projects Settings in your Unity project?
