ICS - NFC tag opens app but does not trigger onNFC event about phonegap-nfc HOT 7 CLOSED

I can't duplicate this. I'm using phonegap-nfc-0.4.0, cordova-1.6.1, sdk-version 15, samsung galaxy nexus (GSM).

Can you send me some info about your setup so I can duplicate this? Can you post or email me the intent from your manifest and the log file from adb logcat?

from phonegap-nfc.

Hi,

I am useing phonegap-nfc-0.4.0 and PhoneGap 1.7.0 (I have tried also on
PhoneGap 1.6.1, but later upgraded project because of the issue).
My phone is Samsung Galaxy Nexus (GSM) and the project is build upon
sdk-version 14 (since my phone works only with v.14).

I have attached project folder where you can find manifest file.

CatLog from my phone is also attached. First I have put NFC card to the
phone and application showed up, but did not triger onNFC event, so no card
information were displayed. I removed the card and left application open.
After a second I have put the same card to the phone again and the
information from the card was displayed.

I hope this will help you evaluate issue.

Thank you for your quick support. I really like your work!

Best regards,
Dejan

Here's what's happening:

Your intent filter in the manifest has a mime-type, so an ndef-mime event is begin dispatched from phonegap-nfc.

<intent-filter>
    <action android:name="android.nfc.action.NDEF_DISCOVERED" />
    <data android:mimeType="text/plain" />
    <category android:name="android.intent.category.DEFAULT" />
</intent-filter>

Your code is listening for ndef events, so it ignores the ndef-mime event that launches the app.

nfc.addNdefListener(onNFC, win, fail);

You can use the same onNFC listener to handle ndef-mime events.

nfc.addMimeTypeListener("text/plain", onNFC, win, fail);

You can keep both the ndefListener and the mimeTypeListener, however once the mimeTypeListener is added you won't see ndef events for plain text tags. Android uses the most specific intent filter when scanning. Also it appears that android treats tags that are TNF WELL_KNOWN RTD type TEXT the same as TNF MIME_MEDIA type "text/plain".

You could switch your code to only have the mimeTypeListener if you don't want it to scan other ndef tags.

Are you creating the NFC tags? You might consider using your own unique mime type "text/centsi", so that your application scans your tags and other applications ignore your tags.

Thank you very much for the explanation and help me solve my issue.

Have a nice day,
Dejan
