Notification Handling for Multiple Devices with the Same User - important

[Kumar-Evoke-Github]

Hello,

I would like assistance with the following scenario:

How to reproduce:

Create two users: A and B.
Log in with user A's credentials on one Android device.
Log in with user B's credentials on two different Android devices.
Start sending notifications from user A to user B.
Both of user B's devices are receiving notifications, but I want only the latest logged-in device to receive notifications. The goal is to have only the most recent device logged in to receive notifications, while older devices do not.
Question: If a user logs in on multiple devices, for example, logging in first on a Samsung Android phone and then on a Google Pixel phone, notifications are currently being sent to both devices. However, I want only the most recently logged-in device to receive notifications.

Is there a way to either delete the old session data without user interaction or implement another solution to ensure only the latest logged-in device receives the notification?

Hello @Kumar-Evoke-Github ,

To implement this logic, Here are the steps that need to be taken:

1. User Authentication:

Perform user sign-in or sign-up.
Link doc:Authentication - QuickBlox

2. Fetch Existing Subscriptions:

After successful authentication, retrieve the list of all current subscriptions.

3. Clear Old Subscriptions:

Iterate through the list of existing subscriptions and delete each one to ensure a clean state.

// Retrieve all existing push notification subscriptions
QBPushNotifications.getSubscriptions().performAsync(object : QBEntityCallback<ArrayList<QBSubscription>> {

// Called when subscriptions are successfully retrieved
override fun onSuccess(subscriptions: ArrayList<QBSubscription>?, bundle: Bundle?) {
    // Iterate through each subscription and delete it
    subscriptions?.forEach { subscription ->
        deleteSubscription(subscription.id)
    }
}

// Called when there is an error fetching the list of subscriptions
override fun onError(error: QBResponseException?) {
    Log.e("PushManager", "Failed to fetch subscriptions: ${error?.message}")
}
})

// Method to delete a subscription
private fun deleteSubscription(subscriptionId: Int) {
try {
    QBPushNotifications.deleteSubscription(subscriptionId).perform()
} catch (e: Exception) {
    Log.e("PushManager", "Failed to delete subscription with ID $subscriptionId: ${e.message}", e)
}
}

4. Create New Subscription:

Once old subscriptions are removed, create a new subscription.

5. Send Events:

After the new subscription is successfully created, event sending can begin.

Looking forward to your feedback.
