I had successfully imported a Module
in my Application project in Android Studio
.
Then I deleted or removed the module by following the below link:
I had this problem when I was trying to add junit 4.12 to my project.First of all I delete old junit codes in dependencies of my build.gradle(app) file manually.Next I deleted the old junit.jar from my library with deleting libs folder and then create new libs folder directory in my app for add library.and for the end.......I find the old junit FILE near the end of project view after gradle folder....you can see in this image......and I deleted it.now I can add new module very easy and without same name error.sorry for bad english!! look this image for last order
