Alternatives for DatatypeConverter in Android

问题:

I trying implement algorithm AES 128 in Android but it doesn't work, the problem is import javax.xml.bind.DatatypeConverter;

DatatypeConverter.parseHexBinary(key) and DatatypeConverter.printBase64Binary(finalData)

Does an alternative exist?

My method:

private static final String ALGORIT = "AES";  public static String encryptHackro(String plaintext, String key) throws NoSuchAlgorithmException, NoSuchPaddingException, InvalidKeyException, IllegalBlockSizeException, BadPaddingException, IOException, DecoderException {       byte[] raw = DatatypeConverter.parseHexBinary(key);      SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");     Cipher cipher = Cipher.getInstance(ALGORITMO);     cipher.init(Cipher.ENCRYPT_MODE, skeySpec);      byte[] cipherText = cipher.doFinal(plaintext.getBytes(""));     byte[] iv = cipher.getIV();      ByteArrayOutputStream outputStream = new ByteArrayOutputStream();     outputStream.write(iv);     outputStream.write(cipherText);      byte[] finalData = outputStream.toByteArray();      String encodedFinalData = DatatypeConverter.printBase64Binary(finalData);      return encodedFinalData;  } 

I see others answers, but I can't implement a solution.

Solution

I solved my problem using

compile 'commons-codec:commons-codec:1.3' 

and I use android.util.Base64 for Android

incompatible / replacement

DatatypeConverter.parseHexBinary  org.apache.commons.codec.binary.Hex.decodeHex(key.toCharArray());     DatatypeConverter.printBase64Binary(finalData); android.util.Base64.encodeToString(finalData, 16)     DatatypeConverter.parseBase64Binary(encodedInitialData); org.apache.commons.codec.binary.Hex.decodeHex(key.toCharArray());
