NfcEvent
public
final
class
NfcEvent
extends Object
Wraps information associated with any NFC event.
Immutable object, with direct access to the (final) fields.
An NfcEvent object is usually included in callbacks from
NfcAdapter. Check the documentation of the callback to see
which fields may be set.
This wrapper object is used (instead of parameters
in the callback) because it allows new fields to be added without breaking
API compatibility.
