i use android studio , lots of code deprecated , data not send php , can't data php

is httpclient expired android studio or i'm wrong?

http client deprecated in api level 22. must use open openurlconnection. can use code

public class fetchurl {      private url url;      public string fetchurl(string urlstring, hashmap<string, string> values) {         string response = "";         try {             url = new url(urlstring);             log.d("url string", urlstring);             httpurlconnection conn = (httpurlconnection) url.openconnection();             conn.setreadtimeout(15000);             conn.setconnecttimeout(15000);             conn.setrequestmethod("post");             conn.setdoinput(true);             conn.setdooutput(true);              outputstream os = conn.getoutputstream();             bufferedwriter writer = new bufferedwriter(new outputstreamwriter(                     os, "utf-8"));             writer.write(getpostdatastring(values));              writer.flush();             writer.close();             os.close();             int responsecode = conn.getresponsecode();              if (responsecode == httpsurlconnection.http_ok) {                 string line;                 bufferedreader br = new bufferedreader(new inputstreamreader(                         conn.getinputstream()));                 while ((line = br.readline()) != null) {                     response += line;                 }             } else {                 response = "";                  throw new exception(responsecode + "");             }         } catch (exception e) {             e.printstacktrace();         }          return response;     }      private string getpostdatastring(hashmap<string, string> params)             throws unsupportedencodingexception {         stringbuilder result = new stringbuilder();         boolean first = true;         (map.entry<string, string> entry : params.entryset()) {             if (first)                 first = false;             else                 result.append("&");              result.append(urlencoder.encode(entry.getkey(), "utf-8"));             result.append("=");             result.append(urlencoder.encode(entry.getvalue(), "utf-8"));         }         log.d("query string", result.tostring());         return result.tostring();     }  }
