You don't need to have an app already on the market to get a Publisher ID for a new app. In the Android Package URL field that's on the "Add Site/App" form, just enter "market://details?id=your.package.name".

The viewWidth warnings are fine and you will likely still see them after inserting your Publisher ID.
