Currently, I'm trying to discover AllJoyn device. Based on Gateway Agent HLD, section 2.3.4, my understanding is that there's a well-defied way to do AllJoyn device discovery. However, I cannot find how gateway agent (GatewayMgntApp) sets Manifest.xml. I only found the get function. My question is that does discovery mechanism have been well-defined in AllJoyn v14.12? Thanks.
