I think AlarmManager can not keep running in case the device has once turned off. This is an explanation extracted from http://developer.android.com/intl/zh-CN/reference/android/app/AlarmManager.html and it told me AlarmManager isn't what I want: Registered alarms are retained while the device is asleep (and can optionally wake the device up if they go off during that time), but will be cleared if it is turned off and rebooted.
