how to perform file upload using Volley in android? -

i want upload files(images,documents etc) android application server.i'm using volley library network calls in application.

i'm using following code upload files not performing operation.(showing volley timeout error finally)

public class multipartrequest extends request<string> {      private multipartentity entity = new multipartentity();      private static final string file_part_name = "file";       private final response.listener<string> mlistener;     private final file mfilepart;     private  string mstringpart,accesstoken;      public multipartrequest(string url, response.errorlistener errorlistener, response.listener<string> listener, file file,string accesstoken)     {         super(method.post, url, errorlistener);          mlistener = listener;         mfilepart = file;         this.accesstoken = accesstoken;         buildmultipartentity();     }      private void buildmultipartentity()     {         entity.addpart(file_part_name, new filebody(mfilepart));         try         {             entity.addpart("content-disposition", new stringbody("form-data"));             entity.addpart("dir_path", new stringbody("izezoje3"));         }         catch (unsupportedencodingexception e)         {             volleylog.e("unsupportedencodingexception");         }     }      @override     public map<string, string> getheaders() throws authfailureerror {         map<string, string> headers = super.getheaders();          if (headers == null                 || headers.equals(collections.emptymap())) {             headers = new hashmap<string, string>();         }          headers.put("content-type", "multipart/form-data");         headers.put("_pkta",accesstoken);           return headers;     }     @override     public string getbodycontenttype()     {         return entity.getcontenttype().getvalue();     }      @override     public byte[] getbody() throws authfailureerror     {         bytearrayoutputstream bos = new bytearrayoutputstream();         try         {             entity.writeto(bos);         }         catch (ioexception e)         {             volleylog.e("ioexception writing bytearrayoutputstream");         }         return bos.tobytearray();     }      @override     protected response<string> parsenetworkresponse(networkresponse response)     {         return response.success("uploaded", getcacheentry());     }      @override     protected void deliverresponse(string response)     {         mlistener.onresponse(response);     } } 

please me on how implement file upload in android(either volley or other)

try

public multipartrequest(string url, string filepath, response.listener<string> listener, response.errorlistener errorlistener) {     super(method.post, url, errorlistener);     entity = new  multipartentity(httpmultipartmode.browser_compatible);     file = new file(filepath);     mlistener = listener;     buildmultipartentity(); } 

also, in case didn't override getheaders, passed other values addpart, e.g:

    entity.addpart("file", new filebody(file, "image/jpeg")); // image     entity.addpart("id", new stringbody(userid)); 

hope helps.
