How to Create Multiple Notifications in Kotlin with a Foreground Service

In this guide, we tackle a common challenge faced by developers: how to create multiple notifications in a Kotlin application that uses a foreground service. This issue typically arises in scenarios such as parental control apps, where parents need to be notified repeatedly about their children's activity status.

Understanding the Problem

You might find that when trying to send multiple notifications from a foreground service implementation, only one notification shows up. This limitation often occurs due to the management of notification IDs or the incorrect configuration of the notification channels.

Example Scenario

For instance, as described by one developer, even though they attempted to send notifications to alert parents about their children's activity statuses, only a single notification appeared. Let's explore how we can solve this problem effectively!

The Solution

The key to creating multiple notifications in a foreground service lies in using unique notification IDs and properly managing both persistent and non-persistent notifications. Here’s a step-by-step breakdown:

Step 1: Setup Notification Channel

Ensure you create a notification channel especially if your app targets Android Oreo (API 26) and above. The notification channel helps manage notifications better.

Step 2: Create Non-Persistent Notifications

You can create non-persistent notifications which automatically disappear once tapped. This is crucial for informing users without cluttering the notification tray.

Step 3: Create a Permanent Notification

While sending multiple alerts, maintaining a permanent notification for the service to run in the background is essential. This alerts the user that the app service is active.

Bringing it All Together

To effectively manage multiple notifications in your background service, you can use an approach like the following:

Set up a unique notification ID for each notification, ensuring they don’t overwrite each other.

Use a combination of persistent and non-persistent notifications.

Maintain a foreground service with a reliable permanent notification.

Conclusion

By implementing these strategies, you can successfully create multiple notifications in your Kotlin application with a foreground service. This setup not only keeps parents informed about their children’s statuses effectively but also enhances the overall user experience.
