Communicate with Android app

[gversluis]

I noticed several ZeppOS apps need Android apps and communicate with those.
Some examples:

• Photo Album by AppMosaic
• Tide Table Chart by AppMosaic
• Camera Remote Watch by AppMosaic
• Navigation War by Navigation Wear

They do not seem to use the fetch API.
Maybe I didn't notice it in the docs but I haven't find an other way to do this.
Does anyone know which API method they use to communicate with those Android applications?

To answer my own question. I just installed WatchDrip+ and did not see any traffic on my VPN no-root firewall either. I assume they do use the fetch API on localhost and my firewall didn't see data to localhost.

In one of the projects I saw this code

	"CONTACTS": async (req) => {
		const response = await fetch({url: "http://10.0.0.103:8080/contacts", method:"GET"})
		const contacts = await response.json()
		return contacts;
	}

But it was a test project and I don't know if such a request to the phone works or not. And of course there was an application on the phone that generated a response to the request.

I myself would like to see some sample code for a simple data exchange between the phone and the watch.
