title: How to disable default Android NFC app when NFC is used in my app
body: <p>In my app I am using NFC to read tags. I click on the button to enable NFC. A progress dialog is opened to read the NFC tag, and when done, NFC is disabled. That's all working fine. But when NFC is not enabled in the app and I put a NFC tag to the phone, the default Android app reads the NFC tag and puts my app to the background.</p>
  
  <p>How can I disable the Android app?</p>
  
  <p>My code for enabling / disabling NFC:</p>
  
  <pre><code>/**
   * @param activity The corresponding {@link Activity} requesting the foreground dispatch.
   * @param adapter  The {@link NfcAdapter} used for the foreground dispatch.
   */
  public static void setupForegroundDispatch(final Activity activity, NfcAdapter adapter) {
      final Intent intent = new Intent(activity.getApplicationContext(), activity.getClass());
      intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
      final PendingIntent pendingIntent = PendingIntent.getActivity(activity.getApplicationContext(), 0, intent, 0);
      IntentFilter[] filters = new IntentFilter[1];
      String[][] techList = new String[][]{};
  
      // Notice that this is the same filter as in our manifest.
      filters[0] = new IntentFilter();
      filters[0].addAction(NfcAdapter.ACTION_NDEF_DISCOVERED);
      filters[0].addCategory(Intent.CATEGORY_DEFAULT);
      try {
          filters[0].addDataType(MIME_TEXT_PLAIN);
      } catch (IntentFilter.MalformedMimeTypeException e) {
          throw new RuntimeException(activity.getString(R.string.exception_wrong_mime_type));
      }
  
      adapter.enableForegroundDispatch(activity, pendingIntent, filters, techList);
  }
  
  /**
   * @param activity The corresponding {@link MainActivity} requesting to stop the foreground dispatch.
   * @param adapter  The {@link NfcAdapter} used for the foreground dispatch.
   */
  public static void stopForegroundDispatch(final Activity activity, NfcAdapter adapter) {
      adapter.disableForegroundDispatch(activity);
  }
  </code></pre>
