Hi, I'm developing an Iotivity client using Java, and I want to observe the presence status of devices.
So I'm using the `OcPlatform.subscribePresence` API, and passing a `OcPlatform.OnPresenceListener` to it. I have a couple of questions about the `onPresence` method: 1. What is the `nonce` argument? The API docs don't explain it. 2. This method only gives me a `hostAddress`, and that's not enough to identify which devices had a presence change, because you can have multiple devices on the same network. Is this an oversight in the Java API? Thanks in advance!
