Enabling Notification

To publish a notification, you must have notification enabled for your application. You can call the requestEnableNotification() API to display a dialog box prompting the user to enable notification for your application. Note that the dialog box is displayed only when the API is called for the first time.

  • Touching allow enables notification for the application, and touching ban keeps notification disabled.

  • The dialog box will not be displayed again when requestEnableNotification() is called later. The user can manually enable notification as follows.

1. Swipe down from the upper left corner of the device screen to access the notification panel. 2. Touch the Settings icon in the upper right corner. On the notification screen, locate the target application. 3. Toggle on Allow notifications.

How to Develop

  1. Import the NotificationManager module.

    import notificationManager from '@ohos.notificationManager';

  2. Call the API to request notification to be enabled.

    notificationManager.requestEnableNotification().then(() => {
    console.info(`[ANS] requestEnableNotification success`);
}).catch((err) => {
    console.error(`[ANS] requestEnableNotification failed, errCode[${err}]`);
});
