Hi,

In my app I'm searching for device with ZeroConf.watch(...). After a timeout I called ZeroConf.close() to stop the service. When I now try to call the ZeroConf.watch(...) again the app crashes. The reason for that is that in ZeroConf.java the jmdns is not set to null.

Here my fix which is working:
...
} else if (action.equals("close")) {
if (jmdns != null) {
try {
jmdns.close();
} catch (IOException e) {
e.printStackTrace();
} finally {
jmdns = null;
}
}
} else if (action.equals("unregister")) {
...

I can call unwatch and than it's working. But when I change the WLAN the I cannot find devices in the new network because we initialize the ZeroConf with an IP.
