Answer 1

@odiiil You can use alarm manager for scheduling notification on specific datetime

Answer 2

for creating a notification use a broadcastReceiver :

public class MyBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {

    Intent resultIntent = new Intent(context,
            MainActivity.class);

    resultIntent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);

    // Because clicking the notification opens a new ("special") activity,
    // there's no need to create an artificial back stack.
    PendingIntent resultPendingIntent = PendingIntent.getActivity(context,
            0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    Notification.Builder mBuilder = new Notification.Builder(context)
    .setSmallIcon(R.drawable.courier_blanc)
    .setContentTitle("Title")
    .setContentText("Message");

    mBuilder.setAutoCancel(true);   
    mBuilder.setPriority(Notification.PRIORITY_MAX);
    mBuilder.setContentIntent(resultPendingIntent);

    // Sets an ID for the notification
    int mNotificationId = 001;
    // Gets an instance of the NotificationManager service
    NotificationManager mNotifyMgr = (NotificationManager) context
            .getSystemService(Application.NOTIFICATION_SERVICE);


    // Builds the notification and issues it.
    mNotifyMgr.notify(mNotificationId, mBuilder.build());

} }

Say if it helps. If you have some questions or if it's not really what you want, say it :)

EDIT :

        int heure = 1;
        int minute = 30;
        Calendar cal = Calendar.getInstance();
        cal.add(Calendar.HOUR, heure); 
        cal.add(Calendar.MINUTE, minute);

        Intent intent = new Intent(this, MyBroadcastReceiver.class);

        PendingIntent sender = PendingIntent.getBroadcast(this, 0, intent,
                PendingIntent.FLAG_UPDATE_CURRENT);

        AlarmManager am = (AlarmManager) this
                .getSystemService(Context.ALARM_SERVICE);

        am.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), minute*60*1000+heure*3600*1000,  sender);
