title: Android NFC Intent-filter for all type
body: <p>I would like to create an Android app that handle all of the NFC event like NDEF, TECH and TAG discovered for all categories and all data types.</p>
  
  <p>These intent filters are in my Android Manifest file:</p>
  
  <pre><code>&lt;intent-filter&gt;
      &lt;action android:name="android.intent.action.MAIN" /&gt;
      &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
  &lt;/intent-filter&gt;
  &lt;intent-filter&gt;
      &lt;action android:name="android.nfc.action.NDEF_DISCOVERED" /&gt;
      &lt;action android:name="android.nfc.action.TECH_DISCOVERED" /&gt;
      &lt;action android:name="android.nfc.action.TAG_DISCOVERED" /&gt;
      &lt;category android:name="android.intent.category.DEFAULT" /&gt;
  &lt;/intent-filter&gt;
  </code></pre>
  
  <p>This code works when the event is TAG_DISCOVERED.
  NDEF_DISCOVERED don't call my app.</p>
  
  <p>Can anyone spot what I'm doing wrong?</p>
