How to recover Gradle files from APK file?

The gradle file is not compiled into the APK, it is only for the actual android studio project for fetching dependencies and app configuration. There is no way to get a gradle file from an APK

Try creating your own folders in the studio and try copying the code into the studio....that should work...and about gradle files? android studio will build it with gradle...as much as i know studio uses gradle build system to build app
