How to use 3DES algorithm on Android?

Question

On the server side, the encyption/decryption of the password field is done in C#.

Now, i need to implement same functionality in my android application. So, i follow

Use this code to encrypt your string

import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;

import android.util.Base64;
//string encryption
public class EncryptionHelper {



    // Encrypts string and encode in Base64
    public static String encryptText(String plainText) throws Exception {
        // ---- Use specified 3DES key and IV from other source --------------
        byte[] plaintext = plainText.getBytes();//input
        byte[] tdesKeyData = Constants.getKey().getBytes();// your encryption key

        byte[] myIV = Constants.getInitializationVector().getBytes();// initialization vector

        Cipher c3des = Cipher.getInstance("DESede/CBC/PKCS5Padding");
        SecretKeySpec myKey = new SecretKeySpec(tdesKeyData, "DESede");
        IvParameterSpec ivspec = new IvParameterSpec(myIV);

        c3des.init(Cipher.ENCRYPT_MODE, myKey, ivspec);
        byte[] cipherText = c3des.doFinal(plaintext);
        String encryptedString = Base64.encodeToString(cipherText,
                Base64.DEFAULT);
        // return Base64Coder.encodeString(new String(cipherText));
        return encryptedString;
    }

}

This is how you can encrypt the string

String encryptedPassword = EncryptionHelper.encryptText(edtText.getText().toString());

EDIT Code for Constants.java

     Class Constants {
         private final String initializationVector = "INITALIZATION_VECTOR";
         private final String ecnryptionKey = "ENCRYPTION_KEY";
         public static String getInitializationVector() {
             return initializationVector;
         }
         public static String getKey() {
             return ecnryptionKey;
         }
     }
