Hongmeng Intelligent Reminder Assistant: 3 steps to realize multi-scene notification📱

Based on Hongmeng agent reminder and delayed tasks, a low-cost and stable reminder system is created. The core logic is as follows:

1. Three major reminder types: trigger on demand⏰

Type Core Scenario Key Parameters Code Sample Snippet
Countdown reminder Conference countdown, cooking timing triggerTimeInSeconds publishReminder({type:'TIMER', trigger:300})
Calendar reminder Birthday, repayment, meeting appointment dateTime/repeatMonths dateTime:{year:2024, month:12, day:31}
Alarm clock reminder Daily wake-up reminder hour/daysOfWeek daysOfWeek:[1,2,3,4,5] (working days)

Unified Publishing Interface

function scheduleReminder(reminder: ReminderRequestBase) {  
  reminderAgentManager.publishReminder(reminder).then(id => {  
console.log('Reminder ID:', id); // Storage ID is used for management
  });  
}
Enter fullscreen mode Exit fullscreen mode

2. Backstage task optimization: low consumption and stability

1. System grouping scheduling policy

Application activity level Minimum reminder interval Applicable scenarios
Active (such as social) 2 hours Instant Message
Commonly used (such as tools) 24 hours Regular data synchronization
Rarely used 48 hours Low frequency cleaning reminder

2. Dynamic resource adaptation

  • Low battery mode: Pause non-emergency reminder when power is <15%. 
  batteryManager.on('levelChanged', (level) => {  
    if (level < 15) cancelAllReminders();  
  });
Enter fullscreen mode Exit fullscreen mode
  • When memory is insufficient: Priority reserves high priority reminders (such as alarm clock) 
  const highPriorityReminder = { priority: 'HIGH', overridePolicy: true };
Enter fullscreen mode Exit fullscreen mode

3. Notification experience optimization: Interaction and beauty are both important✨

1. Custom notification channels 

const reminderSlot = {  
  slotId: 'alarm_channel',  
name: 'Important reminder',
importance: 'HIGH', // pop-up window + ringing + breathing light
vibrationPattern: [100, 200], // Vibration rhythm (milliseconds)
  ledColor: '#FF5733'  
};  
notificationManager.addNotificationSlot(reminderSlot);
Enter fullscreen mode Exit fullscreen mode

2. Interactive button design 

const buttons = [  
  {  
title: 'Train now',
    type: 'ACTION',  
want: { abilityName: 'TaskDetailAbility' } // Click to jump
  },  
  {  
title: 'Reminder after 1 hour',
    type: 'SNOOZE',  
snoozeTime: 3600 // Delay execution
  }  
];
Enter fullscreen mode Exit fullscreen mode

4. Authorization application and compliance📧

Email Template Shorthand:

  • Topic: [Agent Reminder Permission]-Application Name-Brand Name
  • Key points of the text: ✅ Scenario: For example, "Medical App Reminder 3 times a day" ✅ Frequency: Committed to "single user ≤5 items per day" ✅ Close the entrance: "Settings page provides one-click close"

Example:

Apply for daily exercise reminder for "Fitness Assistant". Users can set 3 times a week and click notification to go directly to the training plan.
