I have used an app to stream Android Audio with RTMP, the app is this: https://github.com/mogo29/Android-RTMP
This app asks for a URL like the following: rtmp://dir:port/folder
I've created a server with Red5, and used examples to stream flash videos from a folder on my pc, but I don't know how to do for use my app with this server. I'm sure that I can because I've found this video from the creator of the app: http://www.youtube.com/watch?v=pqUUL0QwuMo
But do you have an real ip at your home where yo make the streaming, because to do that you should have a fixed ip ex 127.0.0.1 and of course the nessesary ports should be open and after that you can put in your Android app the url rtmp://YOUR_IP_ADDRESS:YOUR_PORT/oflaDemo and it should stream.
