             * An NDEF record always contains:
             *
             * * 3-bit TNF (Type Name Format) field: Indicates how to
             *   interpret the type field
             * * Variable length type: Describes
             *   the record format
             * * Variable length ID: A unique identifier
             *   for the record
             * * Variable length payload: The actual data
             *   payload
             *
             * The underlying record representation may be chunked across
             * several NDEF records when the payload is large.
             *
             * NDEFRecord.TNF_WELL_KNOWN - indicates that we are interested
             * in NDEF records of Type Name Format (TNF): "WELL_KNOWN"
             *
             * TNF_WELL_KNOWN included NFC RTD (Record Type Definitions)
             * types such as RTD_TEXT and RTD_URI meaning that they will
             * contain URIs or TEXT suitably encoded according to the NFC
             * RTD specification
             *
             * "Sp" identifies the record type as Smart Poster - so we're
             * only interested in being notified of Smart Poster records
             * that contain plain text or URIs
             *
             * The final parameter "true" identifies that the application
             * will be auto-started if it is not currently running when a
             * smart tag is brought within range of the NFC antenna.
             *
             * This setting is persistent across device power resets.
             *
             * When the application is restarted automatically on
             * presentation of a suitable smart tag to the device the
             * application will be re-started but it is necessary to
             * re-establish the NDEFMessageListener.
             *
             * Upon registering the listener again the tag that caused the
             * application to be re-started is immediately presented to the
             * listener making what is really a two stage process seem
             * seamless.
             *
             * It is important to re-start the listener within about 15 seconds
             * of the application being autostarted. Failure to do so will
             * result in the queued message being lost.
             *
             * There is also no way to determine if the application was
             * autostarted should you wish to automatically restart the
             * listener in this case. Of course you could always leave your
             * own tracks in the sand using the Persistent Store.
             *
             * This behaviour suggests that using the autostart option whilst
             * managing the setting up of the listener via the UI is a combination
             * that can lead to unexpected behaviour.
