AlertDialog Error message keeps on appearing

The Alert Dialog keeps on appearing even if the network is connected. I have checked my code and it is right. Please help.

My main activity class :

package ronitmankad.com.stormy;

import android.content.Context;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.widget.Toast;

import org.json.JSONException;
import org.json.JSONObject;

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();

    private CurrentWeather mCurrentWeather;
    protected void onCreate(Bundle savedInstanceState) {

        String apiKey = "8565fa7afca9865c4475ddd7a84e9c81";
        double latitude = 37.8267;
        double longitude = -122.423;
        String forecastUrl = "https://api.forecast.io/forecast/ " + apiKey +
                "/" + latitude + "," + longitude;

        if (isNetworkAvailable()) {
            OkHttpClient client = new OkHttpClient();
            Request request = new Request.Builder()

            Call call = client.newCall(request);
            call.enqueue(new Callback() {
                public void onFailure(Call call, IOException e) {


                public void onResponse(Call call, Response response) throws IOException {
                    try {
                        String jsonData = response.body().string();
                        Log.v(TAG, jsonData);
                        if (response.isSuccessful()) {
                            mCurrentWeather = getCurrentDetails(jsonData);
                        } else {
                    } catch (IOException e) {
                        Log.e(TAG, "Exception Caught : ", e);
                    } catch (JSONException e) {
                        Log.e(TAG, "Exception Caught : ", e);
                Toast.makeText(this, R.string.network_unavailable_error, Toast.LENGTH_LONG).show();

        Log.d(TAG, "Main UI code is Running");

    private CurrentWeather getCurrentDetails(String jsonData) throws JSONException{
        JSONObject forecast = new JSONObject(jsonData);
        String timezone = forecast.getString("timezone");
        Log.i(TAG, "From JSON:" + timezone);
        return new CurrentWeather();

    private boolean isNetworkAvailable() {
        ConnectivityManager manager  = (ConnectivityManager)
        NetworkInfo networkInfo =  manager.getActiveNetworkInfo();
        boolean isAvailable = false;
        if(networkInfo != null && networkInfo.isConnected()){
            isAvailable = true;
        return isAvailable;

    private void alertUserAboutError() {
        AlertDialogFragment dialog = new AlertDialogFragment();
        dialog.show(getFragmentManager(), "error_dialog");

Actually, your code isn't right :). You've got a space in your URL string which is going to make 'response.isSuccessful()' return false.

Here's the difference in the URL that gets generated. This one has a space after 'forecast/':

https://api.forecast.io/forecast/ 8565fa7afca9865c4475ddd7a84e9c81/37.8267,-122.423

And this one doesn't:
