How to Clear All Notifications in Your Android App with OneSignal

If you're developing an Android application and using OneSignal to manage notifications, you may find yourself needing to clear all notifications when a specific activity is opened by the user. This is a common requirement, especially in applications where notifications represent important updates, like order details. In this guide, we will walk you through how to automatically remove all notifications when your users navigate to the OrdersActivity in your app.

Understanding the Problem

You might have an Android application set up with OneSignal for sending push notifications, such as order updates from your back-end (a PHP-API). The challenge arises when you want to make sure that all the previous notifications are cleared as soon as the user accesses the OrdersActivity. This ensures that users do not see outdated or irrelevant notifications related to past orders.

The Solution

The task can be accomplished simply by calling OneSignal.clearOneSignalNotifications() at an appropriate point in your activity's lifecycle. Let's break this down step-by-step.

Step 1: Verify Your OneSignal Initialization

First, ensure that you have correctly set up OneSignal in your application. The code snippet you provided shows the initialization process. Here it is for reference:

Make sure this initialization code is part of your app startup process, typically in your main application class or the main activity.

Step 2: Clear Notifications in Your Activity

To clear notifications when the OrdersActivity is opened, you should place the clearOneSignalNotifications() method call within the onCreate() or onResume() method of your OrdersActivity. Here’s an example:

Step 3: Test Your Implementation

After you implement the notification-clearing code, you should test your application:

Send a Notification: Use your PHP API to send a test notification to your device.

Open the App: Click on the notification to launch the OrdersActivity.

Verify Notifications are Cleared: Check if the notification has disappeared upon entering the activity.

Conclusion

By following these simple steps, you can easily ensure that all previous notifications are cleared when users access the OrdersActivity in your Android application using OneSignal. This not only improves the user experience but also prevents confusion regarding outdated notifications.
