Steps to reproduce:

Unable to reproduce but seems to be caused by modifications to an immutable list by the firebase performance library

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

Hi @tolulonge, thank you for reaching out. Can you share the versions of the dependency you're using:

• AGP
• Kotlin
• Firebase Perf Gradle Plugin

Have you observed this issue to previous Firebase versions? Also, does the issue occur on certain devices and/or android versions? Thanks!

[tolulonge]

AGP version: 8.8.0
Kotlin version: 2.0.21
Firebase Perf Gradle Plugin: 1.4.2

Yes, it had also been observed in previous firebase versions, it is not unique to the new version
For device distribution, we see mostly samsung devices affected and androd version with highest occurent is Android 14:
88% Samsung, 8% Hauwei, 3% Xiaomi, 3% google and 2% Other
47% Android 14, 22% Android 10, 8% Android 9, 7% Android 12 and 16% Other

[lehcar09]

Thank you for the details @tolulonge. I'll consult this to our engineers and see what we can do here. I 'll get back to you once I hear back from them. Thanks!

[lehcar09]

Our engineers confirmed that this is a bug on Network Request Metric builder with a race condition, which is why it'd be very hard to reproduce. We’re working on this and let you know once the fix is released. Thanks!

[samedson]

@tolulonge thanks for reporting. We haven't been able to reproduce the issue yet, but I wanted to get a better idea about how often this is happening.

I was wondering how many events per week you're getting for this crash? And do you know when this started?

[tolulonge]

Hi @samedson, thanks for looking into this, data is only seen on firebase crashlytics only for as far back as the last 90 days and the issue has been present since then

Approximately, we see 300 events per week for this crash, with total of about 4k crash events in the last 90 days
