title: Access Androids Traffic statistics
body: <p>I would like to monitor the traffic of my mobile hotspot.</p>
  
  <p>I found <code>TrafficStats.getTotalRxBytes</code> but this won't let me monitor precisely the usage of the android mobile hotspot function (or any other app). How can I access the statistic of the <strong>data usage</strong> menue?</p>
