"Unable to find libGfxWXRUnity" when run on device

[MarcLeander]

Hi, we are trying to integrate the Wave SDK into one of our Unity projects to run on a Vive Focus plus. We have followed the installation procedure and upon building and running our application on the device we are only met with a black screen. Investigating the resulting logs shows us the following two potential issues:

...

and also:
...

01-19 15:33:43.023: E/Unity(3161): Unable to find libGfxWXRUnity

Looking into the Unity projects, we can locate a arm64 and a armv7 libGfxWXRUnity.so files. When building the .apk and unpacking it we can find the library at lib/armeabi-v7a/libGfxWXRUnity.so.

Any clues on whether the black screen we are experiencing could be caused by the above errors? Also, why can't the application find the libGfxWXRUnity when its clearly included in the .apk?

@MarcLeander Could you try with a new project?

Could you provide more detailed information such as Unity Editor version and Wave SDK version?

Hi @chengnay, I'm having the same issue.
It's happening in a project that we upgraded, but not in a new one.
I'm trying to use the pass through camera and it's not working (it fails to start), and looking trhough the logcat logs I see this same error that OP mentioned. I'm not sure if this is the reason for the camera failing though.

We are using Unity 2020.1.17f1 and latest versions of sdks

Hi, there may be a solution. It works for me.

All I did is remove "WAVEVR_SINGLEPASS_ENABLED"  from Project Settings->Player->Scripting Define Symbols
and re-import all assets in case.
