what configurations can let unity check Dllimport libname when building.

It is strange. I build two projects on Mac unity 2017.3.1.p4.I will generate a APK and use some native(.so) libraries. I change the library to a wrong name. One project will check and errors happen with "dllnotfoundexception" but another can generate the apk successfully only when installing and running the app the dllnotfound errors are logged.. So I want to know that does it have some configurations on unity to control dllimport check on building or on running???
