android - Import existing project failing in AndroidStudio -

trying use new androidstudio open 1 of eclipse android projects. followed steps , update adt plugin latest version. did export eclipse generating gradle build file.

all went well. when try import androidstudio using existing sources option dialog says:

"source files project not found"

any ideas?

1. add java_home path of jdk(in case "c:\program files\java\jdk1.6.0_38") in environment variable.
2. add android_home path of android sdk(in case "d:\androidsdk") in environment variable.
