Introduction

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

Prototype

public NdefRecord[] getRecords()

Source Link

Document

Get the NDEF Records inside this NDEF Message.

An NdefMessage always has one or more NDEF Records: so the following code to retrieve the first record is always safe (no need to check for null or array length >= 1): 

 NdefRecord firstRecord = ndefMessage.getRecords()[0];
