go get golang.org/x/mobile/cmd/gomobile
~10 minutes later I got the error message
What did you expect to see?
No error message and then being able to run: gomobile build -target=android hello.go
What did you see instead?
I received this error message. gomobile: open /host/projects/golang-prototyping/pkg/gomobile/work-685604373/android-ndk-r12b/platforms/android-21/arch-arm64/usr/include/linux/netfilter/xt_connmark.h: file exists
I'm running this go version inside a Arch Linux Docker container. I installed go, go-tools, etc. (all dependencies) using pacman package manager. My host is Windows 10 64bit and my terminal is "Docker Quickstart Terminal" using VMware and not Hyper-V. Not sure if this is all relevant.
