Do you know if in-app visits to webpages are tracked in Analytics, for example a user browsing inside the facebook app, will he be counted?
Tracking is done based on web beacons(calling Adobe Analytics SDK APIs), so it does not matter if the user is browsing through the app or web view within the app. If you are firing web beacons from within web views you should be able to track the visitors. There is one important aspect you need to consider is to tie the visitors from the app to the web view. You can achieve this by visitor stitching.
