title: Not able to format NFC card using NdefFormatable
body: <p>I am using NdefFormatable class to format my NFC card. The code is like:</p>
  
  <pre><code>NdefFormatable formatable=NdefFormatable.get(tag);
  </code></pre>
  
  <p>But i get formatable reference as null. I checked the code that is run inside the get(tag) method. It checks:</p>
  
  <pre><code>if (!tag.hasTech(TagTechnology.NDEF_FORMATABLE)) return null;
  </code></pre>
  
  <p>I ran <em>"tag.getTechList()"</em> for my tag. I got:</p>
  
  <pre><code>android.nfc.tech.NfcA
  android.nfc.tech.Ndef
  </code></pre>
  
  <p>I was able to format this card using Trigger application. </p>
  
  <p>What can be done to format this.</p>
