Hi @fchristysen, thank you for taking the time for reporting this issue. I am afraid we will need more information from your end in order to better understand what is going on. Can you please provide us with the following information :

• a complete stack trace of the ANR error
• how often this happens, what are the devices model and maybe some scenario through which you are able to reproduce the issue ?

Thanks !!

how often this happens, what are the devices model and maybe some scenario through which you are able to reproduce the issue?

Based on our play store metrics, 0.9% sessions of our users. We put our RUM.enable on our app startup, on our Application class onCreate.

Hello @fchristysen! We have additional questions to continue our investigations:

• Is stacktrace you are posting coming from Play Store?
• Stacktrace from your original message has different methods involved compared to the second stacktrace you've posted (there are some methods in former which don't exist in the latter) - can you give an explanation for this one / post relevant stacktrace?
• Do you see any pattern in your application version (and thus in our SDK version) / OS version / device for the ANRs you are getting?

Hi @0xnm , sorry for late reply

• Is stacktrace you are posting coming from Play Store?
  Yes, it's from Play Store
• Stacktrace from your original message has different methods involved compared to the second stacktrace you've posted (there are some methods in former which don't exist in the latter) - can you give an explanation for this one / post relevant stacktrace?
  Yes, stacktrace from Play Store are from specific user session, I probably copy-paste different one from the original message vs the second one.
• Do you see any pattern in your application version (and thus in our SDK version) / OS version / device for the ANRs you are getting?
  No pattern in Application Version.
  From 89% ANRs are from Android 11 OS
