After leaving a meeting I get an error saying pure virtual function called in /lib/arm/libzoom\_stlport.so and I can’t track down what is making the call. This is my first android app so I suspect I’ve got some sort of life cycle issue where I’m not releasing something. Any help would be greatly appreciated.

SDK Version: 4.3.47200.0322

Device: Pixel 2XL  
OS: Android 9  
Version PQ3A.190705.001

As far as I can tell this is the relevant part of the stack trace.

I just tested and the issue was having a Bluetooth headset connected. If I leave the meeting without my Bluetooth headset connected I do not have the issue. Thank you for your help.
