Hi guys,
I have an Android app, which includes WebView component and some native libraries, such as PDFium.
It is published in Google Play store and while checking the list of reported crashes from users in Google Play Console, I found various crashes/aborts in native code, without any of my classes or bundled libraries mentioned in the stacktrace.
I haven't been able to reproduce any of the crashes (I am not even sure how to emulate them, as I didn't find any hints in the stacktraces). Are those crashes something I should be concerned about? If yes, are there any hints for reproducing / debugging / fixing these crashes?
Some examples from the Google Play Console are below, I appreciate any help/
