Hi @Ihor-SA, thank you for reaching out. I tried reproducing the issue, however, I did not not encounter the same error.

Based on the logs you shared, it looks to me that this is not an SDK issue. Could you share the Android Gradle Plugin version you're using? Also, can you share an MCVE to help us investigate the issue further?

In addition to that, I noticed that you're not using the latest SDK version. Could you try using the latest Firebase SDK version? This is to ensure that you have that latest bug fixes that might be causing the issue. Thanks!

[Ihor-SA]

@lehcar09 thank you for your response. We are currently using Gradle version 8.2.2. Unfortunately, I’m unable to reproduce the issue either, as the report comes from Crashlytics. However, the problem seems to occur on Android versions 10 and above (API level 29+). Our minimum API level is 24, target and compile version is 34, and we’ve set android:installLocation="auto" in the AndroidManifest file.

Thank you for the details @Ihor-SA. From what I gather, this issue is from Firebase dependency androidx.datastore (issuetracker/337870543). It looks like this issue is caused by a race condition where the DataStore file might not exist yet when the read operation begins.

According to this comment:

Sorry for the delay in responding to this issue, as we've seen similar issues in the other bugs and followed up there. This is hard for us to debug as it seems to be a race condition and we cannot easily reproduce it and understand the root cause. Please help us by providing more details (device populations, API levels, or anything you discover as relevant to the bug distribution) from your observation of its occurrence! Also a sample app to reproduce would be great if possible.

In the meantime, I'll try to do some more investigation with the given information. Thanks for your patience.

I'll keep this open for now so that we can keep an eye on it. Thanks!
