androidSnoozeDuration property
How long the snooze action defers this alarm.
Android only. When set, and when NotificationSettings.androidSnoozeButton gives it a label, the alarm notification offers a snooze that stops the current ring and re-registers the alarm this far ahead.
Null, or anything under a minute, offers no snooze. The minimum exists
because Android scheduling stops using AlarmManager for very short
delays, and the fallback survives neither process death nor cancellation.
