Spike of Firebase Performance Monitoring init ANR errors

[Ynnck123]

In the last couple of days we see a spike in ANRs in the step of initializing Firebase performance monitoring

Firebase Status Dashboard https://status.firebase.google.com/summary doesn't show any new incidents so maybe this is something about our code but we didn't do any updates to Firebase in the meantime.

is there a known issue? We are already on 22.0.1 of the firebase performance monitoring library which, looking at the release notes, seems to provide a fix for ANR errors on init.

Thank you for your support.

Hi @Ynnck123, thank you for reaching out. By any chance, have you observe any commonalities for this issue? Does the issue occur on certain devices and/or android versions?

Could you try updating to he latest Firebase SDK version and see if the issue occurrence improves? We usually recommend to use the latest SDK version to ensure that you have the latest bug fixes and improvements.

@lehcar09 thanks for reaching out.

Here is some additional info:

We are currently on Firebase BOM 34.2.0 and performance plugin version 2.0.1.

Important to know: 63% of our users are on Android 16 and 17% on Android 15 so it may has nothing to do with the Android version meaning lower android versions may are also affected.

We updated to the latest Firebase BOM 34.14.0 & performance plugin version 2.0.2 now but will take some time until we can release this version. We cannot reproduce the error so its hard to verify on our end if the update fixes the problems.
