I'm using the jmdns.jar from this project https://github.com/twitwi/AndroidDnssdDemo in my Android project.
I'm currently trying to find all services on my network. I can't use Android NSD, so please avoid suggesting it as a solution.
protected Object doInBackground(Object[] params) {
try {
WifiManager wifi = (WifiManager) getActivity().getSystemService(Context.WIFI_SERVICE);
final InetAddress deviceIpAddress = InetAddress.getByName(Formatter.formatIpAddress(wifi.getConnectionInfo().getIpAddress()));
multicastLock = wifi.createMulticastLock(getClass().getName());
multicastLock.setReferenceCounted(true);
multicastLock.acquire();
jmDNS = JmDNS.create(deviceIpAddress, "Android Device Discovery");
jmDNS.addServiceListener("_http._tcp.local.", new ServiceListener() {//_services._dns-sd._udp _http._tcp.local. _workstation._tcp.local.
@Override
public void serviceAdded(ServiceEvent serviceEvent) {
jmDNS.requestServiceInfo("", "", 1000);
}
@Override
public void serviceRemoved(ServiceEvent serviceEvent) {
}
@Override
public void serviceResolved(ServiceEvent serviceEvent) {
System.out.println(serviceEvent.getInfo().getHostAddress());
System.out.println(serviceEvent.getInfo().getName());
}
});
}catch(IOException e) {
Log.e(TAG, e.getMessage(), e);
}
}
The above code gives me the address and name of a printer on my network. That's great. What I would like is a TYPE that will catch all the services being broadcasted on my network. Android NSD had a _services._dns-sd._udp
that could be used for the type of service and find all services on the network. This doesn't work with jmDNS. I can't find anything in the limited documentation about this.
Do I need to go through and add all the service types myself? That is not a very clean solution.
I have the proper perms in my AndroidManifest.

Try adding the dot at the end, my jmdns app crashed without it.. Also try adding the .local. by yourself with the service type.
