    String forecastURL =  "https://api.darksky.net/forecast/"
            + apiKey + "/" + latitude + "," + longitude;// we will have to refactor it bcoz u want to avoid harcoded text..

      OkHttpClient client = new OkHttpClient();

      //build a request to dark sky api
    Request request = new Request.Builder().url(forecastURL).build();

    //call a request
    Call call = client.newCall(request);
    call.enqueue(new Callback() {
