Using reflection to try and get the DnsSdTxtRecord object from NdsServiceInfo while using [android.net.nsd](http://developer.android.com/reference/android/net/nsd/NsdManager.html) for performing mDNS discovery. This sample uses [fest-reflect](https://github.com/alexruiz/fest-reflect) for reflection.

NsdReflectionUtils.java

import static org.fest.reflect.core.Reflection.*;
import android.net.nsd.NsdServiceInfo;

public class ReflectionUtils {
	public static int extractTxtRecordFromServiceInfo(NsdServiceInfo serviceInfo) {
		Class<?> dnsSdTxtRecordType = type("android.net.nsd.DnsSdTxtRecord")
				.load();
		Object txtRecord = 
				method("getTxtRecord")
					.withReturnType(dnsSdTxtRecordType)
					.in(serviceInfo)
					.invoke();
		int keycount = 0;
		if (txtRecord != null) {
			method("getKeyCount")
				.withReturnType(int.class)
				.in(txtRecord)
				.invoke();
		}
		return keycount;
	}
