Developing App To Stream Media to UPnP devices :Android

Question

Hi,

I am making an application which Streams media from the Internet,it can be from any source like Youtube,or any url. I am able to stream media from my android device.

Now i want to extend it to be streamed to UPnP devices in my network.

Any help on how i can find the list of UPnP devices in my network, then share media with that devices..

I found the little help from http://teleal.org/projects/cling/core/manual/cling-core-manual.html

They have their own API for using UPnP service.

Any body who have worked on UPnP service can help me.

Any help will be much appreciated. Thank you
