List of usage examples for android.nfc NdefRecord NdefRecord
public NdefRecord(short tnf, byte[] type, byte[] id, byte[] payload)
Recommend to use helpers such as {#createUri} or { #createExternal where possible, since they perform stricter validation that the record is correctly formatted as per NDEF specifications.
