how do you read the unique ID of an NFC tag on android?
When working with NFC tags and Android-powered devices, the main format you use to read and write data on tags is NDEF. When a device scans a tag with NDEF data, Android provides support in parsing the message and delivering it in an NdefMessage when possible. Mobile devices that support NFC Technology have the capability to read these tags. In this post we would be talking about NFC Tags that DO NOT contain NDEF data, but instead use their custom. Tag myTag = (Tag) intent.getParcelableExtra(NfcAdapter.EXTRA_TAG); Log.i("tag ID", myTag.getId().toString()); This gives me an ID like "[B@40521c40" but this ID changes every read. Any help would.1.
