Meteor Android REST/DDP Conection

I am trying to connect my app to my MeteorJs application. I the app is logged into, its checks the Meteor DB for the user in the DB, or if not create the new user. I would also like the app to subscribe to the meteor collection so when It is updated its send a notification to the Android App which n turn returns a response.

I have already have rest api set up to take data from my arduino board. But there is no subscription.

I have found this package that uses DDP which seems fine. https://github.com/delight-im/Android-DDP

But when is connects to the Meteor app it says connect to a WEbsocket.

How is the web socket made and work with meteor.

I found this https://github.com/Atmosphere/atmosphere/wiki/Getting-Started-with-Meteor,-WebSocket-and-Long-Polling

but it is written in Java ad I dont see how a collection is attached to some sort of subscription. To me it looks like JSP.

This is probably a very silly question, but i just cant get my head around it.

Thanks
