title: Why MQTT client cannot reconnect?
body: <p>I am writing a MQTT client for Android. I am using ia92 library (wmqtt.jar) and trying to get messages from MQ in order to show them as android notifications. My problem is that the first time I try to connect to the MQ, my android client app successfully connects and MQ messages can be taken normally. When I switch Wi-Fi off and break the network connection, MQTT client connection drops as expected, but when I switch it on again, the app does not establish the MQ connection and throws a MQTTException, that has no error code. </p>
  
  <pre><code>mqttClient.connect(this.mqttClientId, cleanStart, keepAliveSeconds);
  </code></pre>
  
  <p>What can be wrong with this? I heavily need any little bit of help..</p>
  
  <p>Thanks in advance</p>
