java - Uploading Multipart-form-data to php -

i upload data (username, description,..) , photo android-app server (php-script).

by searching found solution: how take photo , send http post request android?

by click on send button, upload-process starts , php-script works $_post -vars empty? can me? request-code:

[...] case r.id.btnsend:     string strname = tname.gettext().tostring();     string stremail = temail.gettext().tostring();     string strdatum = tdatum.gettext().tostring();     string strbeschreibung = tbeschreibung.gettext().tostring();              nvpairs = new arraylist<namevaluepair>(2);     nvpairs.add(new basicnamevaluepair("sender", "andoidapp"));     nvpairs.add(new basicnamevaluepair("name", strname));     nvpairs.add(new basicnamevaluepair("email", stremail));     nvpairs.add(new basicnamevaluepair("datum", strdatum));     nvpairs.add(new basicnamevaluepair("beschreibung", strbeschreibung));     nvpairs.add(new basicnamevaluepair("bild", bmpurl));      new uploadtask().execute(); } [...]  private class uploadtask extends asynctask<void, void, list<string>> {     @override     protected list<string> doinbackground(void... params) {         string response = "";         try {             response = new multipartserver().postdata(new url(posturl), nvpairs);         } catch (ioexception e) {             e.printstacktrace();         }         return null;     }        } 

on multipartserver-code changed line:

if ((avatarname = pair.getname()).equals("avatar")) {     avatarpath = pair.getvalue(); } 

to this:

if ((avatarname = pair.getname()).equals("bild")) {     avatarpath = pair.getvalue(); } 

and variables "bmpurl" , "posturl" set correctly @ line in code.

thanks help! found solution problem. problem @ script how take photo , send http post request android?

i changed this:
