Android App Interacting with Rise API/Servers

Edit Subject

Hi,

I am developing an android app that will need to fetch a list of presentations for a DisplayID then the user will select a presentation and run it. It will then open in the web browser. Does anyone have some code examples of the API in action? A great bonus would be anything relating to the API calls I'll need for this and/or in Java.

Thanks so much for the help, if you need more detail I'm happy to give it!
