• Using Microsoft.MixedReality.OpenXR not found in MRTK3 preview 14 MixedRealityToolkit/MixedRealityToolkit-Unity#125

---

Describe the bug

"using Microsoft.MixedReality.OpenXR;" Not Found during the compilation of Android-based project. There was a missing reference in the assembly definition.

Expected behavior

Your setup (please complete the following information)

• Unity Version [Unity 2021.3.21f1]
• MRTK Version [v3 preview 14]

Target platform (please complete the following information)

• Qualcomm Spades

Additional context

Opening the Microsoft.MixedReality.OpenXR.asmdef in a text editor and adding "Android" as an option in the "include Platforms" section fixed this issue for me.

@jasonodomtaqtile what version of "Mixed Reality OpenXR Plugin" are you using? In version 1.8.0 we have removed support for Android

https://github.com/microsoft/OpenXR-Unity-MixedReality-Samples/releases/tag/v1.8.0

If you still require Android support please downgrade to v1.7.2

https://github.com/microsoft/OpenXR-Unity-MixedReality-Samples/releases/tag/v1.7.2

I've opened a separate issue to remove MRTK3's dependency on the MR OpenXR Plugin for Android

• Remove MRKT3 Android's dependency on MR OpenXR Plugin. #11524

Resolving as Won't Fix, since Android support was removed from the "Mixed Reality OpenXR Plugin"
