Android app wrapped with MDX crashes when performing network request

[Olaf Andreas Oslashvrum]

I am an external consultant developing an app for a customer that wants the app wrapped with MDX, they do their own wrapping. All I do is provide them with the .apk file.

The problem they are seeing is that the application crashes when performing a networking request.

See attached stacktrace of where the crash occurs.

I have no clue on how to debug this since com.citrix.mdx.networking is a private framework not exposing any code.

Is anyone able to point me in the right direction on how to solve this exception?
