Remarks
Send raw NfcA data to a tag and receive the response.
This is equivalent to connecting to this tag via NfcA and calling NfcA#transceive. Note that all MIFARE Classic tags are based on NfcA technology.
Use #getMaxTransceiveLength to retrieve the maximum number of bytes that can be sent with #transceive.
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.
