Facebook integration in cordova app

[Nikola Tesla]

Hi everyone,

I am trying to integrate login using facebook in my app, and i figured out, https://github.com/Wizcorp/phonegap-facebook-plugin is the better way to do it. I actually tried this few times some time back, but there were some other errors due to which i coudnt succeed. I started again, but this time, while adding the plugin only i am getting error 

"Cordova Error : invalid variable format APP_ID" and then its displaying all the core js files in which that error was thrown..Can anyone please help me regarding this issue. Please help me out.
