Android 一例Base64錯誤問題

在Android 11下正常，8.1下不正常
修改import
import org.apache.commons.codec.binary.Base64;
爲
import android.util.Base64;

public static String encrypt(String data) {
        try {
            SecretKey secretKey = new SecretKeySpec(SECRET_KEY.getBytes(), ENCRYPTION_ALGORITHM);
            Cipher cipher = Cipher.getInstance(TRANSFORMATION);
            IvParameterSpec ivParameterSpec = new IvParameterSpec(INIT_VECTOR.getBytes());
            cipher.init(Cipher.ENCRYPT_MODE, secretKey, ivParameterSpec);
            byte[] encryptedData = cipher.doFinal(data.getBytes("UTF-8"));
            return Base64.encodeToString(encryptedData, Base64.DEFAULT);
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }

    public static String decrypt(String encryptedData) {
        try {
            SecretKey secretKey = new SecretKeySpec(SECRET_KEY.getBytes(), ENCRYPTION_ALGORITHM);
            Cipher cipher = Cipher.getInstance(TRANSFORMATION);
            IvParameterSpec ivParameterSpec = new IvParameterSpec(INIT_VECTOR.getBytes());
            cipher.init(Cipher.DECRYPT_MODE, secretKey, ivParameterSpec);
            byte[] decryptedData = cipher.doFinal(Base64.decode(encryptedData, Base64.DEFAULT));
            return new String(decryptedData, "UTF-8");
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }
