Simple Android App (Web View)

To an experienced Android app developer I would imagine this is quite a straight forward project. We have a mobile website offering price comparisons which we want accessing via an android app. The app will simply show a splash page (we will design all the graphics) and from there simply loads the mobile site in the app using webview, and that is essentially it. I should point out that we already have an app which was developed using app inventor which works, but it opens a browser to run the mobile site, and we do not want it to display the address bar etc, and webview is not available for app inventor (which is about the limit of our abilities).
