java - Speedup image upload using Httpurlconnection -

is there way speedup process of uploading image web server. app developing takes long upload image. code works , know able upload image server successfully. based code off of tutorial found here.

  public string uploadfile(string apipath, string filepath, string type)   {     string path = "";     string result = "";      switch (type)     {       case "m":         path = "merchant/" + apipath;         break;        case "c":         path = "customer/" + apipath;         break;     }      log.i(apisecuritymanager.class.getsimplename(), m_token);      string href = "http://tysomapi.fr3dom.net/" + path + "?token=" + m_token;     log.i(apisecuritymanager.class.getsimplename(), href);     try     {       string myip = getip();       string charset = "utf-8";       file file = new file(filepath);        printwriter writer;       outputstream outputstream;        url url = new url(href);       httpurlconnection conn = (httpurlconnection) url.openconnection();        conn.setrequestproperty("user-agent", "java");         conn.setdoinput(true);       conn.setusecaches(false);       conn.setrequestmethod("post");       conn.setrequestproperty("image", file.getname());       conn.setrequestproperty("content-type", "multipart/form-data; boundary = " + boundary);       conn.setrequestproperty("x-forwarded-for", myip);       conn.setdooutput(true);       outputstream = conn.getoutputstream();       writer = new printwriter(new outputstreamwriter(outputstream, charset), true);        writer.append(twohyphens + boundary + line_feed);       writer.append("content-disposition: form-data; name=\"image\"; filename=\"" + file.getname() + "\"" + line_feed);       writer.append("contenttype: image/peg" + line_feed);       writer.append(twohyphens + boundary + line_feed);       writer.flush();        writer.append(twohyphens + boundary + line_feed);       writer.append("content-transfer-encoding: binary").append(line_feed);       writer.append(line_feed);       writer.flush();        fileinputstream inputstream = new fileinputstream(file);       byte[] buffer = new byte[4096];       int bytesread = -1;       while ((bytesread = inputstream.read(buffer)) != -1) {         outputstream.write(buffer, 0, bytesread);       }       outputstream.flush();       inputstream.close();        writer.append(line_feed);       writer.flush();        writer.append(line_feed);       writer.append(twohyphens + boundary + twohyphens + line_feed);       writer.close();        log.i(getclass().getsimplename(), "response code: " + conn.getresponsecode());       if (conn.getresponsecode() != httpurlconnection.http_ok)       {         throw new runtimeexception("failed : http error code : "             + conn.getresponsecode());       }        bufferedreader br = new bufferedreader(new inputstreamreader(           (conn.getinputstream())));        string output;        while ((output = br.readline()) != null)       {         result = result + output;       }        conn.disconnect();     }      catch (         malformedurlexception e         )      {       e.printstacktrace();     }      catch (         ioexception e         )      {       e.printstacktrace();     }      return result;   } 

use library:

it automatically handle url connections, failures & retries.
