[Bug]: Old Notification Displayed When Starting App

[simon1867]

What happened?

An old notification is displayed when starting the app.

Steps to reproduce?

Login
Get a notification
Force stop the app
Launch it later
Old notification is displayed again

What did you expect to happen?

I expected not to see the old notification

OneSignal Android SDK version

5.1.2

Android version

13

Specific Android models

Android Emulator Pixel 3a on API 34

I'm pretty sure the fix is an easy one. NotificationGenerationProcessor.kt line 57 Change if (!isRestoring && isDuplicateNotification(notification)) -> if (isRestoring || isDuplicateNotification(notification))

This is expected restore behavior of the SDK, as the notification was not dismissed or opened by the end-user the notification is restored so it isn't lost. I'll explain in more detail below step-by-step:

1. Get a notification - Displays as expected, SDK saves the data to disk
2. Force stop the app - Android clears all notifications for the app here
3. Launch it later - Android doesn't automatically put the notifications back.
4. Old notification is displayed again - This is behavior the SDK is intently doing

The reason the SDK does this as the end-user may have not looked at their notifications on step 2, so they could have missed them. Since some notifications might be very old and no longer relevant the SDK checks the TTL before restoring them.

@jkasten2 It was mentioned that old notifications would not be displayed again by checking their TTL, but specifically, how much time needs to have passed since receiving the notification for it not to be displayed again?

[jkasten2]

@kishibata The SDK starts the TTL clock when it receives the push in this case. The TTL is 72 hours by default, but you can set that to a different value when sending the notification.
