Help required in finding the ipaddress of the service found

[maheshgupta]

I have successfully found using the browse method in DNSSD class and now I'm trying to find the ipaddress of the found service using queryRecord. Unforutantely I'm not able to get the trigger to the QueryListener that is passed to the queryRecord call. I believe that Im doing something wrong, can you please help me what is the mistake in this code.

try {
            this.browseService = dnssd.browse(SERVICE_TYPE, object : BrowseListener {

                override fun serviceFound(browser: DNSSDService, flags: Int, ifIndex: Int,
                                          serviceName: String, regType: String, domain: String) {
                    LoggingUtil.log("Found in Service " + serviceName + " Domain : " + domain)

                    dnssd.queryRecord(flags, ifIndex, serviceName, 1, 1, object : QueryListener {
                        override fun queryAnswered(query: DNSSDService?, flags: Int, ifIndex: Int, fullName: String?, rrtype: Int, rrclass: Int, rdata: InetAddress?, ttl: Int) {

                            LoggingUtil.log("Found the answer for the Query : " + rdata?.hostName + " - " + rdata?.hostAddress + " _ Address : " + String(rdata?.address!!))
                        }

                        override fun operationFailed(service: DNSSDService?, errorCode: Int) {
                            LoggingUtil.log("Unable to find the address : " + errorCode)
                        }

                    })
                }

                override fun serviceLost(browser: DNSSDService, flags: Int, ifIndex: Int,
                                         serviceName: String, regType: String, domain: String) {
                    LoggingUtil.log("Lost " + serviceName)
                }

                override fun operationFailed(service: DNSSDService, errorCode: Int) {
                    LoggingUtil.log("error: " + errorCode)
                }
            })
        } catch (e: DNSSDException) {
            LoggingUtil.log("error : " + e.message)
        }

Hi, @maheshgupta
You should do Resolve first, than QueryRecords
See my example
