title: How to check a device's nfc capability
body: <p>For an android app that I'm writing, I need to adapt a display based on the nfc capability of the device. Basically, I need to know first if nfc is available, and then to know which features are available (just reading tags, or card emulation,...)</p>
  
  <p>I thought it would be in NfcManager or NfcAdapter but I can't find the right way to perform these tests.</p>
  
  <p>Anyone could help? Many thanks! </p>
