推荐答案

AlarmManager计划意图。如果没有可用的内存，您的服务可能会崩溃并被删除。但是，使用AlarmManager，您可以在计划的时间调用特定的服务。在您的上下文中，AlarmManager比正在运行的服务更好。

AlarmManager schedule the intents. Your service can crash and be removed if memory is not available. But with AlarmManager you can invoke your specific service at a scheduled time. In your context, AlarmManager is a better option than a running service.
