base64 - Java Encode and decode string without forward or backward slash -

-

i have code encode , decode string.

when input "9" encrypt method return "9icoc73f/683bf5wrjdnkq=="

the problem when encode string return encoded string (/ or \ ) , want remove (/ or \ ) string.

so how can achieve encrypt , decrypt both method.

import java.security.key; import javax.crypto.cipher; import javax.crypto.spec.secretkeyspec; import sun.misc.base64decoder; import sun.misc.base64encoder;  public class encryptdecryptaesalgo {     private static final string algo = "aes";     private static final byte[] keyvalue = new byte[] { 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm',             'n', 'o', 'p' };      public string encrypt(string data) throws exception {         string encryptedvalue = "";         try {             key key = generatekey();             cipher c = cipher.getinstance(algo);             c.init(cipher.encrypt_mode, key);             byte[] encval = c.dofinal(data.getbytes());             encryptedvalue = new base64encoder().encode(encval);             return encryptedvalue;         } catch (exception e) {         }         return encryptedvalue;     }      public string decrypt(string encrypteddata) throws exception {         string decryptedvalue = "";         try {             key key = generatekey();             cipher c = cipher.getinstance(algo);             c.init(cipher.decrypt_mode, key);             byte[] decordedvalue = new base64decoder().decodebuffer(encrypteddata);             byte[] decvalue = c.dofinal(decordedvalue);             decryptedvalue = new string(decvalue);             return decryptedvalue;         } catch (exception e) {         }         return decryptedvalue;     }      private key generatekey() throws exception {         key key = new secretkeyspec(keyvalue, algo);         return key;     } }

i using java.

use base64 "url-safe" encoding described in ietf rfc 4648 section 5. replaces + , / characters - , _ respectively. instantiate encoder/decoders follows:

java.util.base64.encoder encoder = java.util.base64.geturlencoder(); java.util.base64.decoder decoder = java.util.base64.geturldecoder();

Android volley - avoid multiple requests of the same kind to the server? -

-
i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response...
