I sometimes get a crash at app startup coming from the nextcloud android-library, debug build.
I use the revision 847558b from 04.Mar.2020 (v2.0.1).
Seems to be related to this problem: jacoco/jacoco#968

Is this really a crash or just an exception?
I see this also from time to time, but the app never crashed…?
Also JaCoCo should only be visible while debugging.

Right. Seems to be an exception only and not inferring a crash. Sorry for the confusion.
However, it would still be nice that this does not show up.

I think you have to add this to your project as it must be in androidTest …

If this is not solved, please re-open.
