Can I play music from my UPnP NAS with VLC on Android? Can I play music from my UPnP NAS with VLC on Android? And if so, how do I find my UPnP device from within VLC?

I'm on the latest beta VLC for Android on a Nexus 4.
No I don't think you can do that directly with VLC.
But you could use another app like BubbleUPnP or UPnPlay, they are made for the purpose.
