Why is the SDK calling a pure virtual function?

I have not been able to reproduce this.

But Google Playstore's automated test catches ones of these EVERY time.

This isn't something we've seen before and we've not had crash reports like this in any of the apps we deploy to the app store.

There is however no escaping the error you are seeing in the log. Some more information would be helpful to track this down. Do you have any information of what the tests are doing at the time of the crash?

Also some clues about your code would help. It's pretty obviously happening when you are calling a MapView.getRotation, but can you tell me a little more about the context you are calling this in?

Also can you confirm what version of the API you are using?
