Android: Handling cookies with Webviews now that Apaches HTTP methods are deprecated? -

i'm trying make post request gives me json. in request, header contains header cookie. later, need attach(?) cookie webview (along proper url).

now apache requests , cookiesyncmanager deprecated, i'm kinda lost.

this code, , doesn't work.

post request code:

    public static string calljsonpost(string urlstring) {      string data = null;      try {         url url = new url(urlstring);         httpurlconnection conn = (httpurlconnection) url.openconnection();          conn.setreadtimeout(10000 /* milliseconds */);         conn.setconnecttimeout(15000 /* milliseconds */);         conn.setrequestmethod("post");         conn.setdoinput(true);         conn.setusecaches(true);          // set cookies in requests         cookiemanager cookiemanager = cookiemanager.getinstance();         string cookie = cookiemanager.getcookie(conn.geturl().tostring());         if (cookie != null) {             conn.setrequestproperty("cookie", cookie);         }          conn.connect();          // cookies responses , save cookie manager         list<string> cookielist = conn.getheaderfields().get("set-cookie");         if (cookielist != null) {             (string cookietemp : cookielist) {                 cookiemanager.setcookie(conn.geturl().tostring(), cookietemp);             }         }          inputstream in = new bufferedinputstream(conn.getinputstream());          data = convertstreamtostring(in);         in.close();      } catch (sockettimeoutexception e) {         e.printstacktrace();     }       return data; } 

webview cookie attachment code:

public class webviewfragment extends fragment {  @override     public view oncreateview(layoutinflater inflater, viewgroup container,                              bundle savedinstancestate) {         view view = inflater.inflate(r.layout.pager_webview_fragment, container, false);          mwvmain = (webview) view.findviewbyid(r.id.mwvmain);          cookiemanager cookies = cookiemanager.getinstance();         cookies.setacceptcookie(true);         cookies.setcookie(murl, "cookie");          mwvmain.loadurl(murl);          mwvmain.setwebviewclient(webviewmanager.sharedinstance());         websettings s = mwvmain.getsettings();         s.setjavascriptenabled(true);         s.setdomstorageenabled(true);         s.setappcacheenabled(true);         s.setallowfileaccess(true);         s.setdatabaseenabled(true);         s.setloadsimagesautomatically(true);         s.setallowcontentaccess(true);          return view;     } } 

what doing wrong?

update after testing, cookie call. remaining question how implement cookie webviews header?
