Read the current android.nfc.NdefMessage on this tag.
This always reads the current NDEF Message stored on the tag.
Note that this method may return null if the tag was in the INITIALIZED state as defined by NFC Forum, as in that state the tag is formatted to support NDEF but does not contain a message yet.
This is an I/O operation and will block until complete. It must not be called from the main application thread. A blocked call will be canceled with IOException if #close is called from another thread.
<p class="note">Requires the android.Manifest.permission#NFC permission.
