The data is not displaying in the logcat and it is showing some random erros

String apiKey = "0123456789abcdef9876543210fedcba";

    double latitude = 42.3601;
    double longitude = -71.0589;

    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() {
        @Override
        public void onFailure(Call call, IOException e) {

        }

        @Override
        public void onResponse(Call call, Response response) throws IOException {
            try {

                //write an if block to know whether the resonse is successful or not
                if(response.isSuccessful()){

Hi Vams.

String apiKey = "0123456789abcdef9876543210fedcba"; is not a valid API key for the DarkSky API. If I remember well, it is a mock key used in their documentation.

You need to register and apply for an API key on their website.

Hope that helps :)

You're welcome. I'm glad you sorted it out :)
