最直截了当的方法是在Project所在目录直接删除整个Project，然后再次打开Android Studio的欢迎界面中把光标移到你的Project上，然后按键盘上的Delete键即可！

Go to File > Reopen Project > Clear list (This will clear the entire recent project list. To delete one project at a time, Go to File > close Project. Now the startup page of android should popup. Select the project you want to delete, press delete on keyboard and say ok).

Close Android studio

Delete the project from C:\users\username\AndroidStudioProjects Now launch android studio :)
