Fixing "Too many field references to fit in one dex file" without MultiDex

Hello everyone,

I'm developing an Android application via Unity 2018.1.6f1, and I'm currently having issues with building it due to reaching the dex limit.

I was wondering what could I remove from these in order to reach the limit? All I added was the Facebook SDK and Firebase SDK and my app wouldn't build anymore. I require a login via Facebook, get friends from Facebook, and Firebase is used for analytics, authentication, database

Code (CSharp):

1. trouble writing output: Too many field references to fit in one dex file: 92331; max is 65536.
2. You may try using multi-dex. If multi-dex is enabled then the list of classes for the main dex list is too large.

Could anyone help with their previous experience in that? I tried enabling MultiDex and building it via Android Studio, but I have 0 knowledge in it and it keeps giving me errors. At some point the application got built - but it keeps crashing(when I try to login). While noting that my editor version of the game is fully functional.

 

Same error here

 

Anyone know how to fix this?
