We require an Android MQTT client (Java and UI) that is able to subscribe and publish at high speeds to a fixed MQTT broker over a local area network. A single page UI should be sufficient.
 Subscribe to multiple topics and based on reading to display a particular image on UI (we currently have specific 41 images).
 Values of the reading should also appear next to the image; to one decimal place.
 Publish a fixed value and topic using a push button on the UI.
 Change Java variable with a slider on the UI.
 Implement the MQTT Eclips Paho library, using IMQTTAsyncClient --- for stability at very high speeds (compared to IMQTTAndroidClient).
[a] The images described in  above should be animated --- i.e. they should transition smoothly if possible.
[b] An indicator on the main page to show if 5 X IP addresses are reachable (possibly using 'ping' --- green on fast, orange on slow, red if very slow/ not reachable).
