This goes on for so long ... I want to import an existing android project into the workspace , but sometimes there is already an existing project with the same name (best example: MainActivitywhich is the most common name, for example, in projects in textbooks)

Therefore, I cannot import a new project into the workspace. Usually I need to delete MainActivity project Abefore I can import project Bwith the same project name. Or ( before ) I need to rename / change to MainActivityand Manifest.xmlfrom project B.
, New Project Name , , .
???
