I'm attempting to write a simple plugin in safari that only needs to check if an application I have developed is installed via javascript. The application launches using a custom uri.
My issue is very similiar to the one presented here, however I'm not developing against iphone\ipad and all I really want is a true\false outcome from my check so that I can present the user with a 'download application or 'launch application' link.
I already have a windows version that works using npruntime for firefox\chrome and ATL for IE which is described here
