Gradle path error for meteor add-platform android - Please Help!

I am using windows 10 and following the meteor whatsapp clone tutorial. When I run the “meteor add-platform android” command, I get the output shown below. I have set the Android_home variable and I can see a gradle folder in my Android Studio directory at C:\Program Files\Android\Android Studio\plugins\gradle. What is the path that I need to update and how do I do it? Any suggestions would be appreciated!
