@ohos.reminderAgent (reminderAgent)

The reminderAgent module provides APIs for publishing scheduled reminders through the reminder agent.

You can use the APIs to create scheduled reminders for countdown timers, calendar events, and alarm clocks. When the created reminders are published, the timing and pop-up notification functions of your application will be taken over by the reminder agent in the background when your application is frozen or exits.

NOTE

This module is deprecated since API version 9. You are advised to use @ohos.reminderAgentManager instead.

The initial APIs of this module are supported since API version 7. Newly added APIs will be marked with a superscript to indicate their earliest API version.
