And Here is My JSOn Array and loop code to make markers

double LAT;
    double LANG;
    String INFO;    
    public List<MapLocation> getMapLocations() {
        if (mapLocations == null) 
        {

        try{
                  jArray = new JSONArray(result);
                  JSONObject json_data=null;
                  for(int i=0;i<jArray.length();i++){
                         json_data = jArray.getJSONObject(i);
                         LAT=json_data.getDouble("lat");
                         LANG=json_data.getDouble("lang");
                         INFO=json_data.getString("info");
                        mapLocations = new ArrayList<MapLocation>();
                        mapLocations.add(new MapLocation(INFO,LAT,LANG));
                     }
                  }
                  catch(JSONException e1){
                      Toast.makeText(getContext(), "No Vehicles Found" ,Toast.LENGTH_LONG).show();
                  } catch (ParseException e1) {
                        e1.printStackTrace();
                }





        }
        return mapLocations;
    }

Please Help to Remove this error

Answer 1

Your class LocationViewers is not being Inflated.
Just make sure that you are using same name at all for com.icons.draw.view.LocationViewers class.

Then another error is about NullPointerException of any object.
