As it develops, more devices using HarmonyOS in the future may emerge, will Godot add export support for the HarmonyOS platform?
Harmony is a rebranded AOSP distro up to version 4, so rebuilding for Android with their SDk should be doable. Edit: Make that an Android build might just run as is on those versions of HarmonyOS.
For versions 5 and up, e.g HarmonyNext, unless Next is a reference to the origins of MacOS X on NextStep with the Mach microkernel, and even then, it’s a major effort on a blank sheet, and it’s a closed source OS, and Huawei is very stringent and picky for developer access : need pictures of your picture ID and sending the photos is no guarantee of access.
Personally not comfortable with sharing my details with a conglomerate with ties to the Chinese military industrial complex and intelligence services.
YMMV,
Cheers!
