Android app crashes on startup.

Hi,
I'm having issues with my app crashing as soon as it starts up. I get the following error trace on logcat:

I know its this package causing it as when I comment out its references the error stops. I assume what is happening is that the unity view is crashing for some reason and because the unity activity runs in parallel with the main activity it also causes that to crash producing the error of modules not being resolved. Is anyone else having or has had a similar issue and if so how did you deal with it?

Many thanks,
Alkis.

@Apetrou What was your solution?

[Apetrou]

It was due to an issue with my unity file. When I fixed the issues in the unity file and re exported it worked fine!

Hey @Apetrou , thanks for reaching out! Can you please describe a bit more in detail what the issue exactly was? Code side? Plugin side? Or something different?
