title: Access NFC tag from a clock app in Android wear
body: <p>I developed a wearable app for Android Wear that read NFC tags. The hardware I used is a Sony Smartwatch 3 modified following instructions on this link: <a href="http://forum.xda-developers.com/smartwatch-3/orig-development/sony-smartwatch-3-nfc-support-package-t3219713" rel="noreferrer">Sony SmartWatch 3 NFC Support Package</a>.</p>
  
  <p>Now my objective is to make a clock app able reading NFC. </p>
  
  <p>Problem is: Android Wear apps are not based on activities but on services, despite the fact that they interact with user and have an output on screen.</p>
  
  <p>Android NFC library has many limitations, one of them (as far as I know) is that it can be used only inside activities.</p>
  
  <p>So my question: is there a way to use Android NFC library (<code>android.nfc.tech.NfcV</code>) and manage NFC tags inside a <code>CanvasWatchFaceService</code> class?</p>
