Native App with WebViews: how to make visits unique across the two worlds?

Hi all,

i have a weird situation with this client: it has a consumer APP which is partially native and partially retrieves page from the web with the webviews.

From the analytics side, this means that site catalyst requests are sent from the native side through the java/ios library, and from the web with the usual javascript code.

Obviously, since these parts don't talk to each other, we got double visits for each user (one visit counted for the native side, one for the web side).

Have you ever met this situation? What do you suggest to make visits unique between the two sides?

Thank you,

Alessandro
