Can you try changing CordovaUnityLauncher.java as follows:

package org.apache.cordova.plugin;

import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;

import org.json.JSONException;
import org.json.JSONObject;

public class CordovaUnityLauncher extends CordovaPlugin
{
	public static class UnityToIonicBroadcastReceiver extends BroadcastReceiver
	{
		@Override
		public void onReceive(Context context, Intent intent) 
		{
			if( intent.hasExtra( "message" ) )
			{
				CordovaUnityLauncher ionicPlugin = CordovaUnityLauncher.getInstance();
				if( ionicPlugin != null )
					ionicPlugin.onMessageReceivedFromUnity( intent.getStringExtra( "message" ) );
			}
			else
				Log.w( "UnityIonic", "No 'message' input is specified in UnityToIonicBroadcastReceiver!" );
		}
	}

	private static CordovaUnityLauncher Instance = null;

	public final int UNITY_LAUNCH_OP = 11;

				cordova.getActivity().sendBroadcast( unityMessage );
			}

				Log.e( "UnityIonic", "exception", e );
			}

			return true;
		}

		return false;
	}
	
	@Override
	public void onStart()
	{
		if (!broadcastReceiverRegistered)
		{
			cordova.getActivity().registerReceiver(broadcastReceiver, new IntentFilter( UNITY2IONIC_SEND_MESSAGE_BROADCAST ) );

	}

		}
	}

	{

		{
			PluginResult result = new PluginResult(PluginResult.Status.OK, "MESSAGE" + message);
			result.setKeepCallback(true);
			callback.sendPluginResult(result);
		}
	}

	@Override
	public void onActivityResult(int requestCode, int resultCode, Intent data) 
	{

			if( resultCode == Activity.RESULT_OK && data.hasExtra("my_param") )
			{
				if (broadcastReceiverRegistered)
				{
					cordova.getActivity().unregisterReceiver(broadcastReceiver);
					broadcastReceiverRegistered = false;
				}
				
				PluginResult result = new PluginResult(PluginResult.Status.OK, "RETURN" + data.getStringExtra("my_param"));

				callback.sendPluginResult(result);
			}
		}
	}
}
