PendingIntent pendingIntent = PendingIntent.getBroadcast(this, ledgerId, intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, 'X seconds in milliseconds', pendingIntent);

2) Use a AlarmBroadCast receiver in your app.

Declare in manifest file :

3) In the broadcast receiver's on receive, you can create the notification.

public class AlarmReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        // create notification here
    }
}
