Thanks for the info here @ihor-monochkov-enverus . The code this references is here https://github.com/appcues/appcues-android-sdk/blob/main/appcues/src/main/java/com/appcues/ui/RequestPermissionActivity.kt#L41. This code executes when an Appcues mobile flow has an element with an action specified to request the push notification permission.

I'm wondering if perhaps this Activity is resuming from the background, in a way that would result in intent being null there unexpectedly. I'll look into this! If you happen to have any other details around how to reproduce this issue or related information from logs, please let us know. Do you know if this stack trace originates from a background resume? Thanks

Firebase Crashlytics says "App 0% in background" - meaning app is in foreground.
To be honest I don't know how to reproduce it. We configured Appcues push notifications in the code, but we have not configured Appcues pushes in Appcues system yet. So I don't know how it is possible to get this crash. But I will work with my team to figure out how it is possible to get this crash and will let you know any details I know.

@iujames Unfortunately, it reproduces again.
Model: OnePlus8Pro
Version: Android 11
Appcues version: 4.3.10

Right now, except of NullPointerException in RequestPermissionActivity.kt:41, I also see:

 Fatal Exception: java.lang.NullPointerException:
       at com.appcues.ui.InAppReviewActivity$onCreate$2.invokeSuspend(InAppReviewActivity.kt:89)

Do you know how it is possible?

Hi @ihor-monochkov-enverus - I believe we can guard against this more carefully as shown in #686 . Please let me know if you have any feedback there. We'll plan to include this in our next update in coming days. Thank you for following up with more information on this issue.

@iujames Looks good. Let me know when it's released so I will upgrade the Appcues version in our app.
