@ohos.reminderAgentManager (Agent-Powered Reminders)

The reminderAgentManager module provides APIs related to agent-powered reminders. When your application is frozen or exits, the timing and notification functions of your application will be taken over by a system service running in the background. You can use the APIs to create scheduled reminders for countdown timers, calendar events, and alarm clocks.

NOTE

The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.
