	                Intent i = new Intent(getApplicationContext(), StatusBarService.class);
	        		getApplicationContext().startService(i);
			}
		});
    }
}

le problème c'est que j'arrive pas savoir le code qui permet de comparer la date saisie par l’utilisateur et la date System pour lancer une notification...
merci d'avance pour votre aide

La date systeme:

En long (milliseconds): System.currentTimeMillis()
En "Date": new Date();
En "Calendar": Calendar.getInstance();

Comparaison de Dates:
d1.before(d2) ou d1.after(d2)

Comparaison de longs:
l1 < l2 ou l1 > l2

Calendar => Date : calendar.getTime();
Date => Calendar: Calendar calendar = Calendar.getInstance(); calendar.setTime(d);

Date => long: date.getTime();
long => Date: new Date(l);
