I have some old MilkMan ANEs & I can export successfully 64bit APKs using the latest Harman Air SDK 33.
But I don't have 64bit Android device to check if they are working as expected.
So, I'd like to ask you if someone tried this before?
No, unfortunately the Milkman ANEs will not work in a 64-bit APK, they don't support the armv8 target. We needed to switch over to a different ANE provider who supports both 32-bit and 64-bit targets, and update our apps for the new ANE instead.
We switched to Distriqt a while back when Milkman stopped properly supporting their ANEs and frankly they are great. Their ANEs are well made, well tested and they are quick and helpful when you need support. They are also great contributors to the AIR/Starling ecosystem.
