"New Tag Collected" instead of reading tags of application - NFC android

Question

I have a class, which creates conncection to NFC and two activites. Both of them creates an object of that class so they can connect to NFC. Earlier it worked somehow but now I've got problem - my application doesn't do anything onNewIntent, even on the first activity. Instead of it, I can see "New tag collected" from build-in app called "Tags" (Nexus S).

What should I do?

class:

public NFCForegroundUtil(Activity activity)
{
    super();
    this.activity = activity;
    mAdapter = NfcAdapter.getDefaultAdapter(activity
            .getApplicationContext());

    mPendingIntent = PendingIntent.getActivity(activity, 0, new Intent(
            activity, activity.getClass())
            .addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP), 0);

    IntentFilter ndef = new IntentFilter(NfcAdapter.ACTION_TAG_DISCOVERED);
    IntentFilter ndef2 = new IntentFilter(NfcAdapter.ACTION_NDEF_DISCOVERED);
    IntentFilter ndef3 = new IntentFilter(NfcAdapter.ACTION_TECH_DISCOVERED);

    try
    {
        ndef2.addDataType("*/*");
    }
    catch (MalformedMimeTypeException e)
    {
        throw new RuntimeException("fail", e);
    }

    mFilters = new IntentFilter[] {ndef, ndef2, ndef3 };

    mTechLists = new String[][] { new String[] {
            // android.nfc.tech.NfcV.class.getName(),
            android.nfc.tech.NfcA.class.getName(),
            android.nfc.tech.IsoDep.class.getName() } };

    mAdapter.enableForegroundDispatch(this, mPendingIntent, mFilters, mTechLists);

}

activity 1:

@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    nfcForegroundUtil = new NFCForegroundUtil(this);

}

 @Override
protected void onNewIntent(Intent intent)
{

    super.onNewIntent(intent);
    Intent i = new Intent(this, NfcDisplayLabelActivity2.class);
    startActivity(i);

 }

Answer 1

Go to settings -> Apps -> All -> Tags(in my case) -> disable

Answer 2

I had a similar problem when trying to open my app from an NFC tag. I had registered an intentfilter in my AndroidManifest.xml for the scheme "magicnfc" and yet it opened the Android OS Tags app instead of mine.

I discovered that the NFC intent (TECH_DISCOVERED in my case) had higher priority than a generic scheme-based intent filter. Because the Tags app registered TECH_DISCOVERED, it was getting opened instead of mine.

Luckily, apps can register for NDEF_DISCOVERED (a higher priority filter) and get opened instead of the Tags app.

That made my app open when I tapped the tag.

More info is here: http://developer.android.com/guide/topics/connectivity/nfc/nfc.html

But I found that I had to override the function onNewIntent, with code like this:

if (NfcAdapter.ACTION_NDEF_DISCOVERED.equals(getIntent().getAction())) {
    String uri = intent.getDataString();

    Parcelable[] rawMsgs = intent.getParcelableArrayExtra(NfcAdapter.EXTRA_NDEF_MESSAGES);
    if (rawMsgs != null) {
        msgs = new NdefMessage[rawMsgs.length];
        for (int i = 0; i < rawMsgs.length; i++) {
            msgs[i] = (NdefMessage) rawMsgs[i];
        }
    }
}

For me, all I needed was:

String uri = intent.getDataString();

Good luck!
