如果我的应用程序没有运行，AlarmManager 会工作吗?

问题描述：

如果我正在与我的应用程序交互(使用)，我有一个警报可以正常工作，但如果我将它设置为第二天而不与我的应用程序交互，它就不起作用.因此我怀疑这是因为我的应用程序过程那时没有运行.

I have an alarm that works fine if i am interacting(using) with my application but it dose not works if I set it for next day and not interacting with my app.Therefore I am getting doubt is this because my application process is not running at that time.

这是我在做什么

Calendar calSet = Calendar.getInstance();
calSet.set(Calendar.HOUR_OF_DAY, selectedhour);
calSet.set(Calendar.MINUTE, selectedminute);
calSet.set(Calendar.YEAR, year);
calSet.set(Calendar.MONTH, monthOfYear);
calSet.set(Calendar.DATE, dayOfMonth);
alarm = new Intent(ActivityA.this, Service.class);
pendingIntent = PendingIntent.getService(getApplicationContext(), i++,alarm, 1);
alarmanager.set(AlarmManager.RTC_WAKEUP, calSet.getTimeInMillis(),pendingIntent);

AlarmManager 提供对系统警报服务的访问.这些允许您安排您的应用程序在未来的某个时间运行.当警报响起时，系统会广播为其注册的 Intent ，如果目标应用程序尚未运行，则会自动启动它.注册的闹钟在设备处于睡眠状态时会保留(如果设备在此期间关闭，可以选择唤醒设备)，但如果关闭并重新启动，则会清除.

简单来说，它会一直工作到您的设备重新启动.

In simple way, it will work until your device has been rebooted.

您可以阅读重启后的Android AlarmManager，其中@CommonsWare 已获得他的链接示例应用程序即使在设备重新启动后仍然存在警报.

You can read Android AlarmManager after reboot where @CommonsWare has been given a link of his sample application which persists Alarm even after device reboot.

请忽略以下部分，它似乎无效.我以后会删除

Please ignore below section, it seems not valid. I will remove in future

~~您可以在 How to create一个持久的AlarmManager，以及如何在应用被杀后保存Alarm? 可以让您了解如何处理此类问题(如果应用程序被终止，则保持警报)~~.

You can read more about application kill at How to create a persistent AlarmManager, and How to save Alarm after app killing? can give you the idea about how to handle such issue (to persist alarm if application has been killed).
