import android.app.AlarmManager;

import android.content.Context;
import android.content.Intent;

import java.util.Calendar;

class AlarmUtils {

    public static void startAlarm(Context context, int type, int index, int hour, int minute, String action) {
        Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(System.currentTimeMillis());
        calendar.set(Calendar.HOUR_OF_DAY, hour);
        calendar.set(Calendar.MINUTE, minute);
        calendar.set(Calendar.SECOND, 0);
        calendar.set(Calendar.MILLISECOND, 0);

        if (calendar.getTimeInMillis() < System.currentTimeMillis()) {
            calendar.setTimeInMillis(System.currentTimeMillis() + (24 * 60 * 60 * 1000));
            calendar.set(Calendar.HOUR_OF_DAY, hour);
            calendar.set(Calendar.MINUTE, minute);
            calendar.set(Calendar.SECOND, 0);

        }

        Intent intent = new Intent(action);
        intent.putExtra("index", index);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(context, index, intent, 0);
        AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
        am.set(type, calendar.getTimeInMillis(), pendingIntent);
    }

    public static void startAlarm(Context context, int type, int index, int interval, String action) {
        Intent intent = new Intent(action);
        intent.putExtra("index", index);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(context, index, intent, 0);
        AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
        am.setRepeating(type, System.currentTimeMillis(), interval, pendingIntent);
    }

    public static void cancelAlarm(Context context, int index, String action) {
        Intent intent = new Intent(action);
        intent.putExtra("index", index);
        PendingIntent sender = PendingIntent.getBroadcast(context, index, intent, 0);
        AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
        am.cancel(sender);
    }
