Example usage for android.nfc NdefRecord NdefRecord

Introduction

In this page you can find the example usage for android.nfc NdefRecord NdefRecord.

Prototype

public NdefRecord(short tnf, byte[] type, byte[] id, byte[] payload) 

Source Link

Document

Construct an NDEF Record from its component fields.

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.

Usage
