Remarks
Get the NdefMessage that was read from the tag at discovery time.
If the NDEF Message is modified by an I/O operation then it will not be updated here, this function only returns what was discovered when the tag entered the field.
Note that this method may return null if the tag was in the INITIALIZED state as defined by NFC Forum, as in this state the tag is formatted to support NDEF but does not contain a message yet.
Does not cause any RF activity and does not block.
