Android UDID like IPhone?

Question

Does Android have a UDID like IPhone? If yes, is there a way I can get it programatically?

Thanks Chris

I implemented a class to get IMEI / Wifi MAC address / deviceID, hope it useful for you ^^

public class DeviceInfo {

protected static String imeiNumber;
protected static String wifiMacAddress;
protected static String deviceID;

// This method must be called before other method
public static void init(Context context) throws Exception {
    imeiNumber = getImei(context);
    wifiMacAddress = getWifiMacAddress(context);
    deviceID = getDeviceId(context);
}

public static String getDeviceInfo() {
    return deviceID;
}

public static String getImei() {
    return imeiNumber;
}

public static String getWifiMacAddress() {
    return wifiMacAddress;
}

public static String getModel() {
    return Build.MODEL;
}

public static String getOsVersion() {
    return Build.VERSION.RELEASE;
}

protected static String getDeviceId(Context context) throws Exception {
    String imei = getImei(context);
    if (imei != null) return imei;
    String tid = getWifiMacAddress(context);
    return tid;
}

protected static String getWifiMacAddress(Context context) throws Exception {
    WifiManager manager = (WifiManager) context
            .getSystemService(Context.WIFI_SERVICE);
    WifiInfo wifiInfo = manager.getConnectionInfo();
    if (wifiInfo == null || wifiInfo.getMacAddress() == null)
        return md5(UUID.randomUUID().toString());
    else return wifiInfo.getMacAddress().replace(":", "").replace(".", "");
}

protected static String getImei(Context context) {
    TelephonyManager m = (TelephonyManager) context
            .getSystemService(Context.TELEPHONY_SERVICE);
    String imei = m != null ? m.getDeviceId() : null;
    return imei;
}

protected static String md5(String s) throws Exception {
    MessageDigest md = MessageDigest.getInstance("MD5");

    md.update(s.getBytes());

    byte digest[] = md.digest();
    StringBuffer result = new StringBuffer();

    for (int i = 0; i < digest.length; i++) {
        result.append(Integer.toHexString(0xFF & digest[i]));
    }
    return (result.toString());
}
}
