Android build instructions out of date

[dabulla]

cd src/conformance
./gradlew clean && ./gradlew build

there is no folder conformance.

I found gradle in hello_xr but building it under arch linux currently fails with this exception for me:

BUG! exception in phase 'semantic analysis' in source unit '_BuildScript_' Unsupported class file major version 65

I try to build OpenXR for Meta Quests.
