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

From source file:Main.java

public static NdefMessage createNdefVCard(String vcard) {
    NdefRecord record = new NdefRecord(NdefRecord.TNF_MIME_MEDIA, MIME_TYPE_VCARD.getBytes(), new byte[] {},
            vcard.getBytes());// ww  w  .j  a v a  2s  .c o m
    return new NdefMessage(new NdefRecord[] { record });
