isSessionSupported('immersive-vr') is false for oculusvrArm64WorldDebug using either openxr or oculus sdk

[nkozakis-csu]

Configuration

Wolvic version: 1.0
Version Code: 41

Hardware: Oculus Quest 2

Steps to Reproduce

I'm trying to build oculusvrArm64WorldDebug for arm64-v8a with webxr working but can't figure out what's going wrong.

• main branch
• versions.gecko_view_nightly = "96.0.20211126093927"
• all third_party sdks present (ovr_moble, ovr_openxr_mobile_sdk, OVRPlatformSdk)
• webxr fails for both user.properties settings openxr=true and openxr=false

Current Behavior

• No VR devices are found by webxr on sample apps found on https://immersive-web.github.io/webxr-samples/
• device capability flags appear to be correct when debugging with position, orientation, present, stageParameters, inline, immersiveVR, and ImmersiveAR set.
• from my debugging and logging I believe externalvr context is registering before gecko runtime starts up

Expected Behavior

Webxr samples should be working like they do with the Igalia apk hosted here

Possible Solution

• wrong branch?
• I noticed the igalia apk download is an oculusvrStore build, would that make a difference?
• building igalia/gecko-dev and using dependencySubstitutions rather than gradle gecko
• I have tried setting fx_config dom.vr.enabled=true but that didn't fix it.

I'll try substituting gecko for igalia/gecko_dev wolvic_release as suggested in this issue #73

That's because we changed the protocol to talk to Gecko. You should use this branch instead https://github.com/Igalia/gecko-dev/tree/wolvic_release. Then in a local.properties file you have to specify:

dependencySubstitutions.geckoviewTopsrcdir=<SOME_PATH>/gecko-dev
dependencySubstitutions.geckoviewTopobjdir=<SOME_PATH>/gecko-dev/obj-aarch64-unknown-linux-android

with your own value for SOME_PATH
