你可能会得到准确的警报，但 处于打盹模式

You might get accurate alarms, but in Doze mode

系统忽略唤醒锁.

所以看起来好像 AlarmManager.setAlarmClock 是唯一可以接受的解决方案，如果您确实需要每 30 分钟触发一次.这可能会抵消所有打盹模式的节能...

So it seems as though AlarmManager.setAlarmClock is the only acceptable solution if you really need to trigger every 30 minutes. This will probably negate all doze mode energy savings...

顺便说一句:似乎您可以使用 adb shell dumpsys alarm 看到警报.

BTW: it seems like you can see alarms with adb shell dumpsys alarm.
