How to get json object from android to php -

-

i trying build web service android app. having problem sending parametres php. using these code blocks http-post.

    public string requestjson(string method, jsonobject parameters) {         try {             int timeout_millisec = 10000;              httpparams httpparams = new basichttpparams();             httpconnectionparams.setconnectiontimeout(httpparams, timeout_millisec);             httpconnectionparams.setsotimeout(httpparams, timeout_millisec);             httpclient client = new defaulthttpclient(httpparams);              string tmpurl = serviceurl.trim() + (serviceurl.trim().endswith("/") ? method : "/" + method);              httppost request = new httppost(tmpurl);              request.setheader(http.content_type, "application/json; charset=utf-8");              if (parameters != null)             {                 request.setentity(new stringentity(parameters.tostring(), http.utf_8));             }              httpresponse response = client.execute(request);              final int statuscode = response.getstatusline().getstatuscode();             final string jsonresponse = entityutils.tostring(response.getentity());              if (statuscode != httpstatus.sc_ok) {                 log.w(tag, "error in web request: " + statuscode);                 log.w(tag, jsonresponse);                 return null;             } else {                 log.i(tag, jsonresponse);                 return jsonresponse;             }         } catch (exception e) {             log.e(tag, "error in fetching json due -> " + e.tostring());         }         return null;     }       public string testfunction() {         try {             jsonobject param = new jsonobject();             param.put("testid", 123);             jsoncevabi = requestjson("test.php", param);              if (jsoncevabi != null) {                 jsonobject jo = new jsonobject(jsoncevabi);                 jsonarray ja = new jsonarray(jo.getstring("d"));                  @suppresswarnings("unchecked")                 list<sampleentity> resultlist = (list<sampleentity>) new gson().fromjson(ja.tostring(), new typetoken<list<sampleentity>>() {                 }.gettype());                 return jsoncevabi;             }             else                 return null;         } catch (exception e) {             return null;         }     }

and php code this;

<?php  $id = json_decode($_post['testid']);   $json = "{d:[{sample1:'".$id."',sample2:'value12'}]}"; $response = $_get["callback"] . $json; echo $response; ?>

what trying sending testid parametre php. , expenting return me value.

but getting {d:[{sample1:'',sample2:'value12'}]}

what want {d:[{sample1:'123',sample2:'value12'}]}

what missing?

edit: found similar question did not help; android json httpclient send data php server httpresponse

as @chandresh_cool said there problem post paramethers. should edit stringentity this: new stringentity("testid="+parameters.tostring(), http.utf_8).

then in server $id variable contains decoded json, should do:

$id = json_decode($_post['testid'], true); $json = "{d:[{sample1:'".$id['testid']."',sample2:'value12'}]}";
