如果我改变电话的时间，报警经理会做什么？

Question

我设置了多个闹钟，为了控制它们，我改变了手机的时间。他们会正常工作吗？换句话说，如果我改变手机的时间，闹钟会崩溃吗？

Answer 1

这一切都取决于您在报警管理器的设置方法中传递的类型。

如果您使用过ELAPSED_REALTIME或ELAPSED_REALTIME_WAKEUP，则不会触发警报

ELAPSED_REALTIME

Added in API level 1
int ELAPSED_REALTIME
Alarm time in SystemClock.elapsedRealtime() (time since boot, including sleep). 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.

如果您有用户RTC或RTC_WAKEUP，将根据设备时间触发警报

RTC

Added in API level 1
int RTC
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.

Answer 2

我不知道崩溃是什么意思。但是警报只能识别设备的时间，所以如果你确实改变了你的设备时间，那么它应该反过来。
