title: Android MQTT unable to create client
body: <p>I am trying to create an mqtt client in my android service using the paho client library . 
  The mosquitto broker is running  on my local machine. 
  I am getting an MqttPersistenceException exception when i try to create a new instance of the MQTTClient.</p>
  
  <p>//create client
  port=1883
  mqttConnSpec="tcp://"+ipaddressOflocalMachine+":"+ port 
  mqttClient =  new MqttClient(mqttConnSpec, mqttClientId)</p>
  
  <p>the exception does not give any reason.
  I am successfully able to communicate using a java console app.
  Is there something extra needed when running this in the android emulator.
  Any help is much appreciated</p>
  
  <p>thanks
  Ben</p>
