title: Device Owner on Android 5.0 (and others) whitout rooted devices, device provisioning by NFC
body: <p>I need to know how to set my application as Device owner in Android 5.0, 4.4 and 4.3(?). I've yet tried the method for rooted devices (<a href="https://stackoverflow.com/questions/21183328/how-to-make-my-app-a-device-owner">described in there</a>), successfully. I saw that works great in android 5.0 and 4.4.2 emulator and in CyanoGen AOSP 4.4.4 (all rooted devices). But I must need to try this on other non rooted devices, in Android 5.0 Developer API you can read this </p>
  
  <blockquote>
    <p>"To deploy and activate a device owner, you must perform an NFC data
    transfer from a programming app to the device while the device is in
    its unprovisioned state."</p>
  </blockquote>
  
  <p>but I don't understand what it means, or better, what I've to do. Can someone help me, or explain me the step to do?</p>
  
  <p>PS. I know what NFC is and how it works but I can't understand how to use for this issue.</p>
