title: Android NetworkInfo state with multiple networks active
body: <p>Fellow developers,</p>
  
  <p>I'm developing an App which requires a use to be on a specific network at all times. I have no problem with listening for the "SUPPLICANT_CONNECTION_CHANGE_ACTION" or "NETWORK_STATE_CHANGED_ACTION". I would like to know what would be returned by </p>
  
  <pre><code>NetworkInfo info = manager.getActiveNetworkInfo();
  info.getSubtypeName();
  </code></pre>
  
  <p>if mutiple networks are active? such as 3/4g and WIFI both active at the same time. I'm unable to test this because i'm testing on a tablet without 3g.</p>
  
  <p>As some of you may realize, this doesn't check for connectivity to a specific WIFI. I have a different solution to that so please don't post answers saying ^^this doesn't work.</p>
  
  <p>I notice calling</p>
  
  <pre><code>manager.getActiveNetworkInfo()
  </code></pre>
  
  <p>returns null if you don't have wifi or 3g turned on.</p>
