AlertDialogue / Error Message keeps on appearing

Alert Dialogue / Error Message keeps on appearing even after I fix the code. There are no error shown, red line or green line in the code. However, when I launch Stormy it show Opps! Sorry! Dialogue Message. I have also reset and change my api key but it is not not working...

Here is my code in MainActivity.java

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

    protected void onCreate(Bundle savedInstanceState) {

        String apiKey = " 9f7caaba306f46b0ce3a72345a890340";
        double latitude = 37.8267;
        double longitude = -122.423;
        String forecastUrl = "https://api.forecast.io/forecast/"+ apiKey +
            "/" + latitude + "," + longitude;

        OkHttpClient client = new OkHttpClient();
        Request request  = new Request.Builder()
                .url (forecastUrl)

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

            public void onResponse(Response response) throws IOException {
                    Log.v(TAG, response.body().string());
                    if (response.isSuccessful()){
                    } else {
                } catch (IOException e){
                    Log.e(TAG, "Exception caught:",e);
        else {
        Log.d(TAG, "Main UI code is Running");

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

    private void alertUserAboutError() {
        AlertDialogFragment dialog = new AlertDialogFragment();
