I used Archive manager on Linux Mint to open the APK of a game made with Unity. To my surprise inside the archive there is a folder under the path /assets/bin/Data/Managed/ that contains almost 10mb of DLL libraries. As far as my understanding goes those should only be useful on Windows running machines. Why would anyone load 10mb of useless data in a 50mb APK? Am I missing something here and DLL libraries can in fact be used by android?
The file command on linux gives this output on the DLLs:
PE32 executable (DLL) (console) Intel 80386 Mono/.Net assembly, for MS Windows
