Answer 1

DLLs run on Windows. They are not cross-platform. In order to run C++ on Android, you must use the Android NDK to compile your native code. You may find the details on this process here .

Answer 2

DLL is used on windows, not on Android.

You can download Android NDK for windows , read ndk example, then modify your code.

Answer 3

我认为* .so可以在Android上使用，因此您需要使用gcc或clang将库编译为* .so二进制文件，而不是使用msvc编译为dll。
