Stormy Weather App: Crashing & Context

Crashing: When the user starts up the app and no available network is detected, a Toast message is displayed. However, when the user taps on the Hourly or Weekly buttons, the app crashes. This issue can be easily fixed with a simple if statement to check if the network is available upon button tap, and if not, an else statement can execute a Toast message notifying the user about the lack of network connection.

    @OnClick (R.id.dailyButton)
    public void startDailyActivity(View view) {
        if (isNetworkAvailable()) {
            Intent intent = new Intent(this, DailyForecastActivity.class);
            intent.putExtra(DAILY_FORECAST, mForecast.getDailyForecast());
            startActivity(intent);
        }
        else {
            Toast.makeText(this, "Network is unavailable!", Toast.LENGTH_LONG).show();
        }
    }

    @OnClick (R.id.hourlyButton)
    public void startHourlyActivity(View view) {
        if (isNetworkAvailable()) {
            Intent intent = new Intent(this, HourlyForecastActivity.class);
            intent.putExtra(HOURLY_FORECAST, mForecast.getHourlyForecast());
            startActivity(intent);
        } else {
            Toast.makeText(this, "Network is unavailable!", Toast.LENGTH_LONG).show();
        }
    }

Context: There is a small discrepancy in ViewGroup's variable name in the HourViewHolder method located within the HourAdapter class. I believe this is due to varying Android Studio versions. Another member provided a solution.
