Please check code below

public class PlacesDisplayTask extends AsyncTask<Object, Integer, List<HashMap<String, String>>> {

        JSONObject googlePlacesJson;
        GoogleMap googleMap;

        @Override
        protected List<HashMap<String, String>> doInBackground(Object... inputObj) {

            List<HashMap<String, String>> googlePlacesList = null;
            Places placeJsonParser = new Places();

            try {
                googleMap = (GoogleMap) inputObj[0];
                googlePlacesJson = new JSONObject((String) inputObj[1]);
                googlePlacesList = placeJsonParser.parse(googlePlacesJson);
            } catch (Exception e) {
                Log.d("Exception", e.toString());
            }
            return googlePlacesList;
        }

        @Override
        protected void onPostExecute(List<HashMap<String, String>> list) {
            googleMap.clear();
            for (int i = 0; i < list.size(); i++) {
                MarkerOptions markerOptions = new MarkerOptions();
                HashMap<String, String> googlePlace = list.get(i);
                double lat = Double.parseDouble(googlePlace.get("lat"));
                double lng = Double.parseDouble(googlePlace.get("lng"));
                String placeName = googlePlace.get("place_name");
                String vicinity = googlePlace.get("vicinity");
                LatLng latLng = new LatLng(lat, lng);
                markerOptions.position(latLng);
                markerOptions.title(placeName + " : " + vicinity);
                googleMap.addMarker(markerOptions);
            }
        }
