Not working on android - Cannot read property 'setScreenName' of undefined'

How do you set this up for android?

I tried to follow the example in the demo folder although I'm using typescript with angular and it works on ios but not on android wher I get `Cannot read property 'setScreenName' of undefined'` (although the pageview doesn't really log since it's a hack to setup a mobile app expecting the tracking code of a website).

Any ideas?
