I have already checked the javadocs of UUID.nameUUIDFromBytes(). Using the same UUID calculation in both Android and j2se as stated below: static String uuid = "0000110100001000800000805f9b34fb"; static byte[] uuid1 = uuid.getBytes(); private static UUID MY_UUID = UUID.nameUUIDFromBytes(uuid1);
It should be the same but in J2SE I am getting "java.lang.IllegalArgumentException" error. Any idea how to solve it?
