Have you tried adding your google analytics html to the index.html file that is in the root of the project?

I haven't tried this myself, but it's possible it will work.

yes , but google analytics  ask me a url To get statistics

Where does it ask for a url?

It needs a domain name to set up and generate your tracking code, but once you have your tracking code you can use it on any url like this:

ga('create', 'UA-XXXXX-Y', 'auto');

Note that you have to use 'auto' instead of the domain name that is in the default html code.

thanks for your help!!!
