The only android app I know of off hand is good ol' Ustream
Never tried it myself, but if the service is still up and running it might work. Pretty sure you need to pay to broadcast.
Um, Ustream is an actual thing :) People, or to give them the credit they deserve, citizen journalists were using it during Gezi Park protests daily over here in Turkey. And yeah, I think that's really cool too.
Also, Periscope keeps your latest broadcast available for replay and can also upload to youtube, but I'm not sure if it's instantaneous like Ustream.
