Class BonjourPublisher

java.lang.Object

com.codename1.io.bonjour.BonjourPublisher

public final class BonjourPublisher
extends Object

Advertises a Bonjour / mDNS service on the local network.

A publisher registers a service of a given type and port; once registered any client on the same network running BonjourBrowser.browse(type, ...) will see it. txt records carry small key/value metadata (typical limit 255 bytes per value).

Example -- advertise an HTTP service on port 8080

BonjourPublisher pub = BonjourPublisher.publish(
        "MyServer", "_http._tcp.", 8080, null);

// when shutting down
pub.unpublish();

On iOS the build pipeline appends type to NSBonjourServices in Info.plist automatically when this class is referenced; without that entry iOS 14+ silently rejects the publish.
