When calling track() of the amplitude SDK, the app crashes with a FileNotFoundException error.
It's a very occasional error, but I don't know the cause.

 

The stacktrace is as follows.

 

E/AndroidRuntime: FATAL EXCEPTION: pool-18-thread-1

Hello @ngJeon hope you are doing well :) 

This is an issue we have been seeing intermittently on our end as well. Thank you for bringing it to our attention in the community.

The engineering team is aware of this issue and has released a fix for it. I recommend upgrading to the newest version of the SDK that was recently released, v1.1.0, here.

Hi! I am seeing a very similar error using v1.7.0, also intermittently, could it be related?
