This plugin is deprecated. Check out the actively maintained fork cordova-plugin-facebook-connect at https://www.npmjs.com/package/cordova-plugin-facebook-connect. I don't experience this Android build error with that plugin, but if you are still running into issues, feel free to open a new issue there.
