public interface NDEFRecordListener
The NDEFRecordListener
provides a mechanism for the application to
be notified, when NDEF records are discovered from the contactless
targets. The notification is requested based on the NDEF record type on the target.
Through this notification the application has a read-only access to the data
on the target, but it has no possibility to open a connection to it.
Applications must implement this interface to
receive the notification.
There can be multiple applications registered to receive notifications
about different NDEF records. If this API is implemented on the MIDP 2.x platform,
the applications can also request startup based on the NDEF record type on the
target with PushRegistry
entries. For more information on that,
see Appendix B: Launching applications with
MIDP 2.x PushRegistry.
The diagram in DiscoveryManager
shows what is the
relationship of this listener to the TargetListener
.
The application is responsible for any possible synchronization required in the listener methods. The listener methods must return quickly and should not perform any extensive processing. The method calls are intended as triggers for the application. The application should do all necessary extensive processing in a separate thread and only use these methods to initiate the processing.
