android - AlarmManager，手机休眠时不调用闹钟

Question

AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
long schedualed = getNextSchedualTime(context);
alarmManager.set(AlarmManager.RTC, schedualed, makeControlPendingIntent(context));

我知道设置 RTC_WAKEUP 即使手机处于 sleep 状态也会运行。但是我想知道当手机处于 sleep 状态时，应该在 sleep 时间触发的RTC闹钟会不会延迟到手机唤醒时？

Answer 1

来自官方文档here :

Alarm time in System.currentTimeMillis() (wall clock time in UTC). This alarm does not wake the device up; if it goes off while the device is asleep, it will not be delivered until the next time the device wakes up.

所以回答你的问题:是的，会延迟，不会掉线。
