我有三个服务。
一个月一次，一个月一次，一个月二次
我用这个代码来初始化它们：

morning_notification = new Intent();
    morning_notification.setClass(this, MorningNotification.class);

    dinner_notification = new Intent();
    dinner_notification.setClass(this, DinnerNotification.class);

    evening_notification = new Intent();
    evening_notification.setClass(this, EveningNotification.class);

在那之后，我这样使用它们：

... 
    /* Запуск сервера */
                        startService(morning_notification);
    ...
 ... 
    /* Запуск сервера */
                        startService(dinner_notification);
    ...
 ... 
    /* Запуск сервера */
                        startService(evening_notification);
    ...

但是，问题是只有MorningNotification服务在工作。但是我需要启动所有三个服务。
我有这个日志：
