Is there a unique Android device ID?

I used below code to get android device IMEI and How can I change below code to get android device Unique ID.

String getDeviceID1(TelephonyManager phonyManager){
    String id = phonyManager.getDeviceId();
    if (id == null){
        id = "not available";
    }
    int phoneType = phonyManager.getPhoneType();
    switch(phoneType){
        case TelephonyManager.PHONE_TYPE_NONE:
            return "" + id;

        case TelephonyManager.PHONE_TYPE_GSM:
            return "" + id;

        case TelephonyManager.PHONE_TYPE_CDMA:
            return "" + id;

        /*
        *  for API Level 11 or above
        *  case TelephonyManager.PHONE_TYPE_SIP:
        *   return "SIP";
        */

        default:
            return "" + id;
    }

    //I used to show IMEI 

    TextView textDeviceID = (TextView)findViewById(R.id.deviceid);
    //retrieve a reference to an instance of TelephonyManager
    TelephonyManager telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
    textDeviceID.setText(getDeviceID1(telephonyManager));
}

In Android, you can get three different Unique Ids.

IMEI ( which you have in your code already )

TelephonyManager telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
String id =  (getDeviceID1(telephonyManager));

Device ID

String android_id = Secure.getString(getContext().getContentResolver(),
                                                Secure.ANDROID_ID);

Bluetooth Address ( this will also be unique for each device )

private BluetoothAdapter mBtAdapter;

// Get the local Bluetooth adapter
mBtAdapter = BluetoothAdapter.getDefaultAdapter();
String deviceMacAddress = mBtAdapter.getAddress();
