Hello all,

I have written several NFC Mifare Ultralight tags in External type (app launcher) with the package name of my Android app. It has no problem in app launching, but my problem is I can't differentiate the launch action was due to user clicks the launcher icon or tag detection. Is there a way I can know it?

Thanks in advance for your help!
