Android NFC start app (using AAR) and read text

I have NFC tag with plain text and AAR. When I tap an NFC to the phone, my app will start. But It just call onCreate() method and don't read the plain text. I have to tap again and then app will read the text.

Can I somehow start app when I tap an NFC and at the sametime read the text?

I use this manual for implement NFC function.

Solution

  • To make sure that you also receive the NDEF message, make sure that you have added an Intent filter for the type of message that is on the tag.
