Integrating google analytics with web version and mobile version of same application

I have an sapui5 application. It has to be deployed to be run on a browser also i have to integrate an pack it as a mobile app using xcode and cordova. Now I have to integrate GA analytics in both web version and mobile version. Question is do i have to use separate tracking ids for each version ? and is there some common method that can be applied so that it works on both versions?
