hi asynktask send multiple data server using 1 @ time have convert string data json format , image in hashmap base64 string format in key value pair unable send getting error base64 string can not serialized please tell me how send image can serlized image , send data server

i have done thing using code :

final byte temp[] = read(fileselected);             // send media             connectiondetector cd = new connectiondetector(getapplicationcontext());             boolean isinternetpresent = cd.isconnectingtointernet();             if(isinternetpresent)             {                 pb.setvisibility(view.visible);                 ibtnsendchatnote.setenabled(false);                 final string soap_action = "http://xxxxx/xxxxxx/insertmedia";                 final string method_name = "insertmedia";                 final string namespace = "http://xxxxx/";                 thread networkthread = new thread() {                 @override                 public void run() {                   try {                         soapobject request = new soapobject(namespace, method_name);                         soapserializationenvelope envelope = new soapserializationenvelope(soapenvelope.ver11);                         envelope.setoutputsoapobject(request);                         new marshalbase64().register(envelope);                         httptransportse ht = new httptransportse(ipconfig.url);                         request.addproperty("sid", sid);                         request.addproperty("notecontent", filepath[filepath.length-1]);                         request.addproperty("notetype", "mobile");                         request.addproperty("mediacontent", temp);                                                   ht.call(soap_action, envelope);                         final soapprimitive sp = (soapprimitive) envelope.getresponse();                          runonuithread (new runnable(){                             public void run() {                                 pb.setvisibility(view.gone);                                                 ibtnsendchatnote.setenabled(true);                                 if(sp.tostring().equals("true"))                                 {                                     // ever want                                 }                                 else                                 {                                     toast.maketext(getapplicationcontext(), "error while sending", toast.length_short).show();                                 }                                 ibtnsendchatnote.setenabled(true);                              }                          });                   }                   catch (exception e) {                       e.printstacktrace();                   }                 }                 };                 networkthread.start();             }             else             {                 toast.maketext(getapplicationcontext(), "please connect internet!", toast.length_short).show();             } 

get byte[] using filepath

public static byte[] read(string filepath) {         try {             file file = new file(filepath);             fileinputstream fis = new fileinputstream(file);             byte[] b = new byte[(int) file.length()];             fis.read(b);             fis.close();             return b;         } catch (exception ex) {             return null;         }     }
