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.
|
||
|
|
|
||
|
|
<p>Here's a summary of the classes:</p>
|
||
|
|
|
||
|
|
<dl>
|
||
|
|
<dt>{@link android.nfc.NfcManager}</dt>
|
||
|
|
<dd>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}.</dd>
|
||
|
|
<dt>{@link android.nfc.NfcAdapter}</dt>
|
||
|
|
<dd>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)}.</dd>
|
||
|
|
<dt>{@link android.nfc.NdefMessage}</dt>
|
||
|
|
<dd>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.</dd>
|
||
|
|
<dt>{@link android.nfc.NdefRecord}</dt>
|
||
|
|
<dd>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.</dd>
|
||
|
|
</dl>
|

|

<p class="note"><strong>Note:</strong>
|

Not all Android-powered devices provide NFC functionality.</p>
