Flip Clock
Introduction
This sample uses the Feature Ability (FA) model and related APIs to implement a simple flip clock app. Below shows the sample app.
Concepts
reminderAgent: a class that provides 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.
Required Permissions
ohos.permission.PUBLISH_AGENT_REMINDER (permission for the reminder agent)
ohos.permission.RUNNING_LOCK (permission for the running lock)
ohos.permission.NOTIFICATION_CONTROLLER (permission for send notification)
