getDailyForecast() and getHourlyForecast() don't return anything.

Here is my code, the code is the same for the getDailyForecast() method.

    private Hour[] getHourlyForecast(String jsonData) throws JSONException {
        JSONObject forecast = new JSONObject(jsonData);
        String timezone = forecast.getString("timezone");
        JSONObject hourly = forecast.getJSONObject("hourly");
        JSONArray data = hourly.getJSONArray("data");

        Log.v("HORSEDATA", data.toString());

        Hour[] hours = new Hour[data.length()];

        for(int i = 0 ; i < i; i++){
        JSONObject jsonHour = data.getJSONObject(i);
        Hour hour = new Hour();

            hour.setSummary(jsonHour.getString("summary"));
            hour.setTemp(jsonHour.getDouble("temperature"));
            hour.setIcon(jsonHour.getString("icon"));
            hour.setTime(jsonHour.getLong("time"));
            hour.setTimezone(timezone);
            hour.setPrecip(jsonHour.getDouble("precipProbability"));

            hours[i] = hour;
        }
        return hours;
    }

Tried calling the through Forecast.class and without it, same result.

Was that a typing error in your for loop? You have while i < i instead of i < data.length()
