Exporting a 64bit Android app that uses TinCan (xAPI)


I'm using the Unity game engine to develop an Android app. It's using the TinCan.NET xAPI library for tracking user activity.

The app already works when built to Android with the "Mono" scripting backend. But when I switch to "IL2CPP" (for the Google Play 64bit requirement), I suddenly have build issues with the TinCan.dll and any script that uses it. It gives me a "
No action for the assembly TinCan, Version=, Culture=neutral, PublicKeyToken=7e2d97554f738180 defined" Linker error.

This is the best tutorial I've come across. He only uses "Mono", and even in the comments, he acknowledges that it doesn't work on IL2CPP for him and someone calls out the apparent lack of support for IL2CPP/64bit.

tl;dr: Is there a way to build 64bit APK/AAB with TinCan?
