Old Android App Compile

I have an app which was programmed long ago using Eclipse which supported native functions using *.so files and presently I am unable to use the same source using Android Studio / Eclipse. I need help with compiling this file using Android Studio so that I can make changes to this app. This might need some minor tweaking on the source but since this is urgent, I am posting this here for experts. Please let me know if you can compile this on Android Studio. The bid deliverables are corrected code / instructions so that new app can be compiled on Android Studio.
