I've read through android documentation on finding specific network services using NSD. Below is my code to discover all the available _http._tcp
services.
final NsdManager.DiscoveryListener discoveryListener = new NsdManager.DiscoveryListener() {
@Override
public void onDiscoveryStarted(String s) {
Log.i(TAG, "onDiscoveryStarted: " + s);
}
@Override
public void onServiceFound(NsdServiceInfo nsdServiceInfo) {
Log.i(TAG, "onServiceFound: " + nsdServiceInfo.toString());
}
@Override
public void onServiceLost(NsdServiceInfo nsdServiceInfo) {
Log.i(TAG, "onServiceLost: " + nsdServiceInfo.toString());
}
@Override
public void onDiscoveryStopped(String s) {
Log.i(TAG, "onDiscoveryStopped: " + s);
}
@Override
public void onStartDiscoveryFailed(String s, int i) {
Log.i(TAG, "onStartDiscoveryFailed: " + s);
}
@Override
public void onStopDiscoveryFailed(String s, int i) {
Log.i(TAG, "onStopDiscoveryFailed: " + s);
}
};
final NsdManager manager = (NsdManager) getSystemService(Context.NSD_SERVICE);
manager.discoverServices("_http._tcp", NsdManager.PROTOCOL_DNS_SD, discoveryListener);
Till this point everything's working fine. However, I'm wondering how to find all the available services on the network using this approach? I can see there are a dozen of different services (e.g. _ipp._tcp, _airport._tcp, _airplay._tcp, _atc._tcp and many more) available on my local network using ZeroConf browsing apps found on Google PlayStore.
Is there any wildcard that allows to gather all the available services through single discovery-listener since I couldn't find such information on developer pages?
change your service with _services._dns-sd._udp i have too and it working in nsd but in jmdns its not working
