[FreeBSD]developping Android application on FreeBSD

I'm interested in programming Android Application. Now I'm trying to program on FreeBSD.
If you have any information about this, please let me know(sanpei FreeBSD dot org)

Android Studio

• Windows(guest) on VirtualBox on FreeBSD(host)
• edit and compile[OK], USB debug[Slow,NG]
• unfortunately USB2 is not supported on VirtualBox/FreeBSD, so it's very slow to deply your apk to real mobile phone

•  Linux(guest) on bhyve(grub-bhyve)  on FreeBSD(host)
• edit and compile[OK], USB debug[NG]
• Run Android Studio, but currently it can't connect mobile phone via USB.
• I'm trying to passthrough PCI/USB to guest OS. but currently I can't.
