Not able to retrieve weather data from forecast.io

As the title says, I'm unable to retrieve data from the site and I can't figure out why. Any help would be greatly appreciated

Here is my main activity code:

package com.example.puneetmahal.stormy;

import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.util.Log;

import java.io.IOException;

import okhttp3.Call; import okhttp3.Callback; import okhttp3.OkHttpClient; import okhttp3.Request; import okhttp3.Response;

public class MainActivity extends AppCompatActivity {

public static final String TAG = MainActivity.class.getSimpleName();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    //put api key that you got from URL here, break is down into the following components
    String apiKey = "7ec60e1b37c24a1742a89ad7213654b3";
    double latitude =37.826;
    double longitude = -122.423;
    String forecastURL = "https://api.forecast.io/forecast" + apiKey + "/" + latitude + "." + longitude;

    //main client object
    OkHttpClient client = new OkHttpClient();
    Request request = new Request.Builder()    //Build request with the url
            .url(forecastURL)                 //Pass in the URL
            .build();                        //actually builds it

    //Need a call obj, need to put this request inside a call object.
    Call call = client.newCall(request);    // we have an execute method from the call class
                                            //and it returns a response object. Lets put that in a var

    call.enqueue(new Callback() {
        @Override
        public void onFailure(Call call, IOException e) {

        }

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

                if (response.isSuccessful()) {
                    Log.v(TAG, response.body().string());    //around 7 min mark on Making an HTTP Get request.
                }

            } catch (IOException e) {
                Log.e(TAG, "Exception caught ", e);
        }
    }


    });


}

}

And here is the logcat with filter "show only selected application":

Your String forecastURL setup is not correct. You have: String forecastURL = "https://api.forecast.io/forecast" + apiKey + "/" + latitude + "." + longitude;

Change it to: String forecastURL = "https://api.forecast.io/forecast" + apiKey + "/" + latitude + "," + longitude;

Hope it helps!

Happy coding!

Write down your forecastURL string value?

It should work: String forecastURL = "https://api.forecast.io/forecast" + apiKey + "/" + latitude + "," + longitude;

The string is fine, I actually get a JSON back. On debugger it looks like the problem is in parsing the JSON data into my model for some reasons. Thanks anyway!
