On Android, I was able to go live using an app called Ace Live Streaming.
Hit the three line icon in the top left, then select custom, Add Dlive as a bookmark and paste you stream url as provided by Dlive, then append a /streamKey to the end of it. It should look like rtmp://stream.dlive.io/live?key=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx==/{StreamKey}

Then just press the circle in the top right and your good! Hope this helped!
