Exemple d'un émulateur de tag NDEF

Bonjour
Voici l'exemple d'utilisation d'un émulateur de tag NDEF sous Android:

public static NdefMessage createMessage(String text, boolean encode) {
NdefRecord[] records = new NdefRecord[1];
records[0] = createRecord(text, Locale.FRENCH, encode);
return new NdefMessage(records);
}

public static NdefRecord createRecord(String text, Locale locale,
boolean encode) {
byte[] langBytes = locale.getLanguage().getBytes(
Charset.forName("US-ASCII"));
Charset utfEncoding = encode ? Charset.forName("UTF-8") : Charset
.forName("UTF-16");
byte[] textBytes = text.getBytes(utfEncoding);
int utfBit = encode ? 0 : (1 << 7);
char status = (char) (utfBit + langBytes.length);
byte[] data = new byte[langBytes.length + textBytes.length + 1];
data[0] = (byte) status;
System.arraycopy(langBytes, 0, data, 1, langBytes.length);
System.arraycopy(textBytes, 0, data, 1 + langBytes.length,
textBytes.length);
return new NdefRecord(NdefRecord.TNF_WELL_KNOWN, NdefRecord.RTD_TEXT,
new byte[0], data);
}
