Apple's open-source mDNS/DNS-SD implementation mDNSResponder underlies Android's NSD API, so I could one day see seamless interoperability over Wi-Fi Aware being a thing. I wouldn't bet on it happening, but given Windows (which ships with an mDNS/DNS-SD stack) and Android will be doing it before too long, I wouldn't be surprised to see Apple join the party.

I hope we'll one day see proper support for mdns in Android. Devs shouldn't have to go out of their way to use the special NSD API to provide mdns functionally in their apps. It should just work at the system level, which to be clear, it does not. It's been years and years in this state, so I can't be as positive.

Incidentally, Wi-Fi Aware is based heavily on AWDL but the Wi-Fi Alliance made a number of breaking protocol changes in the Wi-Fi Aware standard. This isn’t exactly Apple’s fault - it could have been interoperable.
