title: Use Barcode Scanner + with intent from Xamarin Android app
body: <p>I'm developing an app (for a single customer) with Xamarin that must read barcodes with the camera (and optionally with an external bluetooth scanner), and used for testing an Asus TF300T, a LG4xP880 and a Nexus 7 second edition (the target machine).</p>
  
  <p>I tested ScandIt and ZXing, but the best results I had with the free Barcode Scanner app (same library of ZXing, I know, but can't get the same speed).
  I've read that I can use it with an intent, and I can also buy the plus version (need portrait scanning), but I couldn't find any documentation on how to (if possible), with intent call only:</p>
  
  <ul>
  <li>configure the layout, select portrait/landscape</li>
  <li>select the barcode type (exclude some)</li>
  <li>insert a button that exits scanning without reading </li>
  </ul>
  
  <p>Is it possible?</p>
