Any plans for arm64/aarch64 support?

I was trying to build Elemental and selected “latest” for most version values. And I have an aarch64 device attached, so the system tried to build for it and I get the below error. I assume by a web search that turned up an answer on here about disabling arm64 that the new ABI isn’t supported yet.

Would compiling my own copy of UE help?

OneOfMany07,

Please try a different version of Android such as Android-21. That should support what you’re trying to package for. Let me know the results.

Thanks!
