Description Dagfinn 2015-10-23 09:09:02 UTC
We are getting the exception below when the android version of the app starts when the MainActivity inherits from FormsApplicationActivity, but not when it inherits from Activty. It also only occurs in Release mode, both with and without linking. What could be causing this?

Could you possibly upload a reproduction project as well as system information in order to help investigate the issue?
