Android API级别10（2.3.3）中的NoClassDefFoundError AES128位

Question

我正在使用以下代码对数据进行加密和解密。

这是我的ENcoder通话

public class BASE64Encoder extends CharacterEncoder {

    /** this class encodes three bytes per atom. */
    protected int bytesPerAtom() {
        return (3);
    }


    protected int bytesPerLine() {
        return (57);
    }

    /** This array maps the characters to their 6 bit values */
    private final static char pem_array[] = {
            // 0 1 2 3 4 5 6 7
            'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', // 0
            'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', // 1
            'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', // 2
            'Y', 'Z', 'a', 'b', 'c', 'd', 'e', 'f', // 3
            'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', // 4
            'o', 'p', 'q', 'r', 's', 't', 'u', 'v', // 5
            'w', 'x', 'y', 'z', '0', '1', '2', '3', // 6
            '4', '5', '6', '7', '8', '9', '+', '/' // 7
    };



    protected void encodeAtom(OutputStream outStream, byte data[], int offset,
            int len) throws IOException {
        byte a, b, c;

        if (len == 1) {
            a = data[offset];
            b = 0;
            c = 0;
            outStream.write(pem_array[(a >>> 2) & 0x3F]);
            outStream.write(pem_array[((a << 4) & 0x30) + ((b >>> 4) & 0xf)]);
            outStream.write('=');
            outStream.write('=');
        } else if (len == 2) {
            a = data[offset];
            b = data[offset + 1];
            c = 0;
            outStream.write(pem_array[(a >>> 2) & 0x3F]);
            outStream.write(pem_array[((a << 4) & 0x30) + ((b >>> 4) & 0xf)]);
            outStream.write(pem_array[((b << 2) & 0x3c) + ((c >>> 6) & 0x3)]);
            outStream.write('=');
        } else {
            a = data[offset];
            b = data[offset + 1];
            c = data[offset + 2];
            outStream.write(pem_array[(a >>> 2) & 0x3F]);
            outStream.write(pem_array[((a << 4) & 0x30) + ((b >>> 4) & 0xf)]);
            outStream.write(pem_array[((b << 2) & 0x3c) + ((c >>> 6) & 0x3)]);
            outStream.write(pem_array[c & 0x3F]);
        }
    }
}

类用于解码器

public class DataEncryptor 
{
    static char[] carr = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f' };

    public static synchronized String encryptPassword(String input) 
    {

        MessageDigest digest = null;

        try 
        {
            digest = MessageDigest.getInstance("MD5");
        }
        catch (Exception ex) 
        {
            ex.printStackTrace();
        }

        if (digest == null)
            return input;

        try 
        {
            digest.update(input.getBytes("UTF-8"));
        }
        catch (java.io.UnsupportedEncodingException ex) 
        {
            ex.printStackTrace();
        }

        byte[] rawData = digest.digest();
        BASE64Encoder bencoder = new BASE64Encoder();
        return bencoder.encode(rawData);
    }
}

这是我的活动，我想对我的数据进行加密和解密

@Override
                     protected void onPostExecute(JSONObject json)

                     {
                      super.onPostExecute(json);

                       try
                         {

                           int randomNum = generateUniqueId();
                           RequestId  =System.currentTimeMillis()+""+randomNum;

                             json.put(KEY_REQUEST_ID, RequestId);
                             json.put(KEY_REQUEST_CODE, RequestCode);
                             json.put(KEY_CHANNEL_ID, stringChannelId);
                             json.put(KEY_IP_ADDRESS, str_Device_IP_Address);
                             json.put(KEY_USERNAME, strUserName);
                             json.put(KEY_PASSWORD, strPassWord);

                                String jstr = json.toString();
                                System.out.println("jstr =" +jstr);

                                String reqvalues=AES128Bit.encrypt(json.toString(),key);
                                System.out.println("reqvalues =" +reqvalues);

                                JSONObject jSONObject = new JSONObject();
                                jSONObject.put(KEY_REQUEST, reqvalues);
                                jSONObject.put(KEY_VENDOR_ID, "1");
                                String jsonString = jSONObject.toString();
                                System.out.println("jsonString =" +jsonString);


                                JSONObject outer = new JSONObject();
                                outer.put("W2INBCWS", jsonString);
                                String outerJSONObjectResponse=outer.toString();
                                System.out.println("outerJSONObjectResponse =" +outerJSONObjectResponse);

                              //  outerJSONObjectResponse=outerJSONObjectResponse.replace("true", "\"true\"");
                               // JSONObject dataJSONObject = new JSONObject(outerJSONObjectResponse);

                               // String strGetResponseFromJson=dataJSONObject.getString("Response");
                                String strGetResponseFromJson = AES128Bit.decrypt( outerJSONObjectResponse ,key); 
                                System.out.println("strGetResponseFromJson =" +strGetResponseFromJson);



                         } 

                         catch (JSONException e)

                         {
                            e.printStackTrace();
                         } 

                         catch (Exception e) 
                         {
                            // TODO Auto-generated catch block
                            e.printStackTrace();
                        }

                       pDialog.dismiss();

                     }

                     }

当我运行应用程序时，我的应用程序崩溃了，并得到了错误和异常。 这是我的日志猫堆栈跟踪

Answer 1

com.anm.cms.core.util.AES128Bit在类路径中不存在，我在您的代码中看到您正在使用它。

String reqvalues=AES128Bit.encrypt(json.toString(),key);
String strGetResponseFromJson = AES128Bit.decrypt( outerJSONObjectResponse ,key);

当我们在普通的Java类中遇到此类问题时，以下是建议遵循

找出其.jar文件并将其放在您的类路径中。 假设您的jar文件名为ABC.jar和要在Main.java中运行的java文件，然后使用以下命令运行程序

java -cp C：\\ ABC.jar主要
