可能是google在sun官司上吃亏了，现在基本上相关的java代码在google上也有一套新的实现。近几天在客户端post 内容加密的时候就遇到了类似的问题，在java的服务器端使用apache的base64的库就可以正常使用，在安卓端就遇到了问题，报错不支持Apache commons-codec，这就尴尬了，服务器的代码不能拿来用在客户端。那么没办法了就再找一个方式，发现安卓有自带的Base64 库。
以下只是贴安卓端的代码实现:

import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;
import android.util.Base64;


public class AESOperator {
    /*
     * 加密用的Key 可以用26个字母和数字组成 此处使用AES-128-CBC加密模式，key需要为16位。
     */
    private String sKey = "1234567890123456";//key，可自行修改
    private String ivParameter = "0987654321098765";//偏移量,可自行修改
    private static AESOperator instance = null;

    private AESOperator() {

    }

    public static AESOperator getInstance() {
        if (instance == null)
            instance = new AESOperator();
        return instance;
    }

    public static String Encrypt(String encData ,String secretKey,String vector) throws Exception {

        if(secretKey == null) {
            return null;
        }
        if(secretKey.length() != 16) {
            return null;
        }
        Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
        byte[] raw = secretKey.getBytes();
        SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");
        IvParameterSpec iv = new IvParameterSpec(vector.getBytes());// 使用CBC模式，需要一个向量iv，可增加加密算法的强度
        cipher.init(Cipher.ENCRYPT_MODE, skeySpec, iv);
        byte[] encrypted = cipher.doFinal(encData.getBytes("utf-8"));
        //return Base64.encodeBase64String(encrypted);
        return Base64.encodeToString(cipher.doFinal(encrypted),Base64.DEFAULT);// 此处使用BASE64做转码。
    }


    // 加密
    public String encrypt(String sSrc) throws Exception {
        Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
        byte[] raw = sKey.getBytes();
        SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");
        IvParameterSpec iv = new IvParameterSpec(ivParameter.getBytes());// 使用CBC模式，需要一个向量iv，可增加加密算法的强度
        cipher.init(Cipher.ENCRYPT_MODE, skeySpec, iv);
        byte[] encrypted = cipher.doFinal(sSrc.getBytes("utf-8"));
        //return Base64.encodeBase64String(encrypted);// 此处使用BASE64做转码。
        return Base64.encodeToString(encrypted,Base64.DEFAULT);
    }

    // 解密
    public String decrypt(String sSrc) throws Exception {
        try {
            byte[] raw = sKey.getBytes("ASCII");
            SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");
            Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
            IvParameterSpec iv = new IvParameterSpec(ivParameter.getBytes());
            cipher.init(Cipher.DECRYPT_MODE, skeySpec, iv);
            byte[] encrypted1 = Base64.decode(sSrc.getBytes(), Base64.DEFAULT);// 先用base64解密
            //Log.i("HttpRequest","encrypted1 is:"+encrypted1.toString());
            byte[] original = cipher.doFinal(encrypted1);
            //Log.i("HttpRequest","original is:"+original.toString());
            String originalString = new String(original, "utf-8");
            //Log.i("HttpRequest","originalString is:"+originalString);
            return originalString;
        } catch (Exception ex) {
            return null;
        }
    }

    public String decrypt(String sSrc,String key,String ivs) throws Exception {
        try {
            byte[] raw = key.getBytes("ASCII");
            SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");
            Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
            IvParameterSpec iv = new IvParameterSpec(ivs.getBytes());
            cipher.init(Cipher.DECRYPT_MODE, skeySpec, iv);
            byte[] encrypted1 = Base64.decode(sSrc.getBytes(), Base64.DEFAULT);// 先用base64解密
            byte[] original = cipher.doFinal(encrypted1);
            String originalString = new String(original, "utf-8");
            return originalString;
        } catch (Exception ex) {
            return null;
        }
    }

    public static String encodeBytes(byte[] bytes) {
        StringBuffer strBuf = new StringBuffer();

        for (int i = 0; i < bytes.length; i++) {
            strBuf.append((char) (((bytes[i] >> 4) & 0xF) + ((int) 'a')));
            strBuf.append((char) (((bytes[i]) & 0xF) + ((int) 'a')));
        }

        return strBuf.toString();
    }
}

在安卓中重要的是代替的Base64
关键代码:
Base64.encodeToString(cipher.doFinal(encrypted),Base64.DEFAULT);// 此处使用BASE64做转码。
