title: What does enableForegroundDispatch and disableForegroundDispatch do?
body: <p>I read the documentation and I don't quite understand what either do. Considering Android made the puzzling decision that we now need to use Android Beam to send data from 1 one phone to another and there is no way to simultaneously send data from both to both, I don't see the use.</p>
  
  <p>Can't I just call <code>setNdefPushMessage</code> on one phone, and have an <code>onNewIntent</code> callback in the other phone which does something if <code>NfcAdapter.ACTION_NDEF_DISCOVERED.equals(intent.getAction())</code> is true?</p>
  
  <p>What is the point of <code>enableForegroundDispatch</code> and <code>disableForegroundDispatch</code>?</p>
