An error occurs when building Android for 2022.3.62f2.

SPECIFIC ISSUE ENCOUNTERED

I’m developing an Android app with Unity 2022.3.62f2.
After updating cardboard_xr_unity to 1.31.0 and building, a Gradle build error occurs.
The error details are as follows:

/==== error start =====/

ERROR:xxx/.gradle/caches/transforms-3/a5d277e50699cd47e756d4c4a066f1f7/transformed/jetified-GfxPluginCardboard-runtime.jar: D8: java.lang.NullPointerException

FAILURE: Build completed with 2 failures.

What went wrong:

/===== error end =====/

cardboard_xr_unity is installed via UPM.

I understand that Unity 2022.3 is not officially supported, but this application has already been released, and it’s difficult to upgrade to Unity 6000 immediately.
Do you know how to resolve the build error?

VERSIONS USED

What version of Google Cardboard are you using?
Cardboard SDK/Cardboard XR Plugin 1.31.0

If you are using Cardboard XR Plugin:

• What version of Unity are you using?
  2022.3.62f2

Probably for this reason

So, after going through and fixing more than seven projects to migrate to Google’s new mandatory SDKs, and fixing a critical Unity bug across all projects, they decide to remove support for these Unity versions in their own Cardboard tool due to a problem they themselves created with the 16 KB file system. For some reason, I’m starting to think they don’t want us to use their tools.

I’m really frustrated; six months of work wasted.

Edit: If you want to launch the app, you can do so using Cardboard version 1.30.1, which works with Unity 2022. The problem is that in the future you’ll need to update to Unity 6000, because Google doesn’t allow you to update your app unless the 16 KB patch is applied in the Cardboard asset (1.31.0 or later).
