    I know how to export a project to Android Studio and get it running just fine. However, when I was pouring over the files in Android Studio, I got to thinking how exactly does Unity translate/compile everything over? Unity runs on Mono, which was .NET for Linux essentially. Now I am wondering how it translates that into java code for Android.

    After much research, I found it has a lot to do with the Java Native Interface, which allows you to port things over essentially to Java from C#. Unfortunately, this is all buried in Java packages which would need to be decompiled (Unity uses FernFlower decompiler)

    Java code is not translated, it goes into your apk. JNI is used for interop between it and native code.
