SMS Scheduler 在特定时间用于短信

Question

例如，我节省了 6:00 和 6:05 的时间，然后当我开始服务时，将在 6:00 发送第一条消息，而不会发送第二条消息。这里 Timer 类无法正常工作我不知道为什么？请帮助我。清单文件是正确的

，这是我的代码

考虑使用 BuzzBox SDK 来安排您的短信。将您的 sendSms 代码放入任务中，并使用类似以下内容来安排任务：

SchedulerManager.getInstance()
    .saveTask(this, "0 6 * * 1,2,3,4,5,6,7|5 6 * * 1,2,3,4,5,6,7", SmsTask.class);

其中 cron 字符串表示将您的任务安排在每天的 6:00 和 6:05。
SDK 将处理剩下的事情。
