Bonjour implementation on Android

Question

I am trying to implement bonjour/zero conf on my android app. I am using jmDns library for searching the all the available devices. Here is the code that I am using for sear

Answer 1

As noted in comments above, the native Android support is not working and/or not implemented completely to allow retrieval of TXT records (as of Android v5.1). I also could not get the jmDns library to work for discovery. I finally found the mdnsjava project and it worked very easily for me. Note that its sample code is not correct. Here is some sample of code I used to synchronously find all IPP printers:

    String type[] = {"_ipp._tcp.local."};
    Lookup resolve = null;
    try {
        resolve = new Lookup(type, Type.ANY, DClass.IN);
        ServiceInstance[] records = resolve.lookupServices();
        for (ServiceInstance record : records) {
            Log.d(TAG, record.toString());
            Map txtMap = record.getTextAttributes();
        }
    } catch (IOException e) {
        e.printStackTrace();
    }

Also note that you need to add the dnsjava library to your libs folder and your build.gradle. I used version 2.1.7.
