Получение ошибки в этой строке, как только я нажму кнопку выбора 

 LatLngBounds bounds=builder.build();

Пробовал много способов, например, использовать API-ключ браузера вместо API-карты Google Maps 

private void getDirection() {

        currentPosition= new LatLng(mLastLocation.getLatitude(),mLastLocation.getLongitude());
        String requestAPI=null;
        try{
            requestAPI="https://maps.googleapis.com/maps/api/directions/json?"+"mode=driving&"+
                    "transit_routing_preference=less_driving&"+"origin="+currentPosition.latitude+","+
                    currentPosition.longitude+"&"+"destination="+destination+"&"+"key="+getResources().getString(R.string.google_map_API_key);
            Log.d(TAG, "getDirection: requestAPI");
            mService.getPath(requestAPI)
                    .enqueue(new Callback<String>() {
                        @Override
                        public void onResponse(Call<String> call, Response<String> response) {
                            try {
                                JSONObject jsonObject= new JSONObject(response.body().toString());
                                JSONArray jsonArray=jsonObject.getJSONArray("routes");

// checking if polylineList is Empty or not
