A library jar that provides APIs for Applications written for the Google Android Platform.
Provides access to Near Field Communication (NFC) functionality, allowing applications to read
NDEF message in NFC tags. A "tag" may actually be another device that appears as a tag.
For more information, see the
Near Field Communication guide.

Here's a summary of the classes:
- {@link android.nfc.NfcManager}
- This is the high level manager, used to obtain this device's {@link android.nfc.NfcAdapter}. You can
acquire an instance using {@link android.content.Context#getSystemService}.
- {@link android.nfc.NfcAdapter}
- This represents the device's NFC adapter, which is your entry-point to performing NFC
operations. You can acquire an instance with {@link android.nfc.NfcManager#getDefaultAdapter}, or
{@link android.nfc.NfcAdapter#getDefaultAdapter(android.content.Context)}.
- {@link android.nfc.NdefMessage}
- Represents an NDEF data message, which is the standard format in which "records"
carrying data are transmitted between devices and tags. Your application can receive these
messages from an {@link android.nfc.NfcAdapter#ACTION_TAG_DISCOVERED} intent.
- {@link android.nfc.NdefRecord}
- Represents a record, which is delivered in a {@link android.nfc.NdefMessage} and describes the
type of data being shared and carries the data itself.
Note:
Not all Android-powered devices provide NFC functionality.
