How to set a notification using a broadcast reciever

Receiver class

public class NotificationPublisher extends BroadcastReceiver {

@Override

NotificationManager notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);

Notification notification = intent.getParcelableExtra(NOTIFICATION);
int id = intent.getIntExtra(NOTIFICATION_ID, 0);
notificationManager.notify(id, notification);

}
}

Main Class
private void scheduleNotification(Notification notification, Calendar cal) {

 int newid = NotificationID.getID();
 Intent notificationIntent = new Intent(this, NotificationPublisher.class);

 //making the intent unique
 notificationIntent.setAction("actionstring" + System.currentTimeMillis());

 //Sending variables to the Broadcast Reciever
 notificationIntent.putExtra(NotificationPublisher.NOTIFICATION_ID, newid);
 
 notificationIntent.putExtra(NotificationPublisher.NOTIFICATION, notification);

 PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

 AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
 alarmManager.set(AlarmManager.RTC, cal.getTimeInMillis(), pendingIntent);
 }
