    The OpenXR documentation site states that the provider plugin should work with any external OpenXR runtime available on the system. While this seems to work on windows, I haven't had any luck with this on Android, where the method of runtime discovery is different (using ContentProvider) compared to standalone (JSON). I am trying to use Monado's android OpenXR runtime with installable broker on a regular device instead of Oculus.

    Please find the android logcat text below for reference. Note that I am able to test the runtime with Khronos hello_xr application, so it's likely some configuration issue from Unity (if not limitation). Would appreciate if you can confirm on following:
    1. Whether or not it's possible to link to an external OpenXR runtime on Android (other than Oculus)?
    2. If so, then what's the configuration is like for in-process and out-of-process runtime?

    Thanks,

    Thanks for the extension package! This was exactly what I was looking for. Unfortunately when I launched it on an android phone the openxr loader failed to detect the monado openxr runtime, even though its installed installed and linked by the broker (tested with the hello_xr sample application).
    Maybe you can share a bit more information about your setup. Thanks in advance!

    I am facing the same issue. The app opened but did not connect to the monado runtime. Can you please share more details?

    It's been a while, but couple of things to check would:
    - Selecting the correct Monado runtime (i.e. in-process or out-process)
    - Android permissions and manifests merge after Unity build
    - Android API level and graphics API settings from Unity.

    Can you open a Github issue here, with any console logs for the errors. I would rather be prompt in replies there.
