java - JSON Exception when trying to retrieve object string -

I am trying to retrieve the "Maxspeed" string from JSON I runs through this array, but When it reaches the "tag" object and tries to achieve the "maximized" value, then it gives an exception (below)

will anyone know why this is happening is?

Exception:

  org.json.JSONException: no value for maxspeed  

java:

  JSONObject parentObject = new JSONObject (result); JSONArray speedJSON = parentObject.getJSONArray ("element"); For (int i = 0; i   
 
 < P> You are trying to get maxspeed from  element , but it is not there. The object is in the  element  in the  tag . 
 
 You want something like 
 
  if (! Element IsNull ("tags")) {JSONObject tag = element.getJSONObject ("tags"); String maxspeed = tags.getString ("maxspeed"); TxtSpeed.setText (MaxSpeed ​​+ "here"); } Else {// your error handling here ...}
