On the code of OpenXR CTS which is published in github, you have explained how to build on Windows and Linux, however, Android is not included. Why not provide it about Android?
Right now, there is not a cross-vendor loader for OpenXR on Android. If/when there is one, a build system will be provided.
I see you are a member: Get in touch with the WG on this internal issue. https://gitlab.khronos.org/openxr/openxr/-/issues/1425
