Consuming OData channel service from SAP NWGW in iOS/Android thru SUP 2.1

Greetings,

I am trying to find some documentation or tutorial to explain how to write a Native application (iOS or Android) that can consume an OData channel from Netweaver gateway.

What needs to be done on SUP server (or Data Proxy as the case may be) to make this happen?

So far I haven't been successful in turning up any such tutorial.

Appreciate your time.

Thanks
