Android Wifi Direct Service Discovery
android, android-wifi, bonjour, wifi-direct
Solution
Finally figured it out.. kind of. When getting an instance of a service request, I was specifying the service instance name and type to match the values used when creating the service...
Registering the service: `mServiceInfo = WifiP2pDnsSdServiceInfo.newInstance(Consts.SERVICE_INSTANCE, Consts.SERVICE_REG_TYPE, record);`
Creating the service request: `mServiceRequest = WifiP2pDnsSdServiceRequest.newInstance(Consts.SERVICE_INSTANCE, Consts.SERVICE_REG_TYPE);`
I removed the arguments to the newInstance method when getting the service request... `mServiceRequest = WifiP2pDnsSdServiceRequest.newInstance();`
and both listeners are being called now. It seems like my first method would filter out other services being broadcasted nearby, which is why I originally opted for that overload.
Problem
I'm trying to implement a simple android application that broadcasts a WifiP2p bonjour service on one device and have a second device discover and connect to it. I've pretty much followed the tutorial here. I have a valid `Channel` object, a `DnsSdServiceResponseListener`, and a `DnsSdTxtRecordListener`, and set them via this call: ``` mManager.setDnsSdResponseListeners(channel, servListener, txtListener); ``` As of right now both listeners just spit out some debugging info to keep it real simple. The problem is that my `DnsSdServiceResponseListener` is never called, but the `DnsSdTxtRecordListener` does get called and all the arguments passed in look legit. How can one be called but not the other? I am testing using two actual devices, both running android 4.2.2. Thanks!
