php - org.json.JSONObject cannot be converted to JSONArray while i retrive data from MYSQL -

i have made php code array of data mysql struggling android

php code:

if ($_server['request_method'] == 'get') {     $user_id = $_get['user_id'];      require_once('dbconnect.php');      $user_tags = array();      foreach ($_request['user_id'] $key => $val) {         $user_tags[$key] = filter_var($val, filter_sanitize_string);     }      $user_ids = "'" . implode("','", $user_tags) . "'";     $sql = "select * user_tags user_id in ({$user_ids})";     $r = mysqli_query($con, $sql);     //creating blank array      $result = array();     //looping through records fetched      while ($row = mysqli_fetch_array($r)) {         $result['tags'][] = $row['tags'];        }      //displaying array in json format      echo json_encode(array('result' => $result));      mysqli_close($con); } 

this gives result:{"result":{"tags":["pascol","php","python"]}}

when try toast "tags" in android error:

    rg.json.jsonexception: value {"tags":["pascol","php","python"]} @ result       of type org.json.jsonobject cannot converted jsonarray 

my android code:

  public class jobs extends appcompatactivity {    public static final string data_url =    "http://allwaysready.16mb.com/sort.php?work[]="; public static string tags="";  private string json_string; public static final string tag_json_array="result"; public static final string key_user_tags="tags";  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_jobs);      getemployee();      toast.maketext(getapplicationcontext(),tags,toast.length_long).show();     toast.maketext(getapplicationcontext(),"hi",toast.length_long).show();     check();  }      private void getemployee(){     class getemployee extends asynctask<void,void,string>{         progressdialog loading;         @override         protected void onpreexecute() {             super.onpreexecute();             loading = progressdialog.show(jobs.this,"fetching...","wait...",false,false);         }          @override         protected void onpostexecute(string s) {             super.onpostexecute(s);             loading.dismiss();             showemployee(s);         }          @override         protected string doinbackground(void... params) {             requesthandler rh = new requesthandler();             string s = rh.sendgetrequestparam(config.url_get_tag,userareaactivity.id);             return s;         }     }     getemployee ge = new getemployee();     ge.execute(); }  private void showemployee(string json) {     try {         jsonobject jsonobject = new jsonobject(json);         jsonarray result = jsonobject.getjsonarray(tag_json_array);         jsonobject c = result.getjsonobject(0);        string ttags = c.getstring(key_user_tags);         tags=ttags.tostring();     } catch (jsonexception e) {         e.printstacktrace();     } } 

i think response coming jsonobject. trying convert jsonarray.

try this,

    jsonobject valuejsn = new jsonobject(response);     jsonarray tags =valuejsn.getjsonarray("tags");
