I am trying to get JmDNS to work in my android program. I am able to get it to discover the devices I want, but I do not fully understand how to get the information from JmDNS to the object that started the JmDNS task. Here is my code.
protected void browse() {
try {
jmdns = (JmDNSImpl) JmDNS.create();
jmdns.addServiceListener(type, listener = new ServiceListener() {
public void serviceResolved(ServiceEvent ev) {
}
public void serviceRemoved(ServiceEvent ev) {
}
public void serviceAdded(ServiceEvent event) {
DNSEntry addressEntry = jmdns.getCache().getDNSEntry(name, DNSRecordType.TYPE_A, DNSRecordClass.CLASS_ANY);
if (addressEntry instanceof DNSRecord) {
ServiceInfo cachedAddressInfo = ((DNSRecord) addressEntry).getServiceInfo(true);
if (cachedAddressInfo != null) {
for (Inet4Address address : cachedAddressInfo.getInet4Addresses()) {
//I need to get the address that is here back out of this listener to the main thread
}
}
}
}
});
} catch (IOException e) {
e.printStackTrace();
}
The problem I am running into is that I have a service manager object that has a instance of a browser object that has the browse method in it. I am unable to get the service manager object access to the address variable. Because JmDNS spawns its own thread when it is created to run its tasks I have tried to use a handler and runnable to send messages with the variable in it but I cant seem to get it right. Can anyone help?
I think you want to just use the ServiceEvent event object passed into the service added method. It has all the info you need.
