I would recommend you re-read the earlier post from Marcin. Let your web page detect a Mobile browser and display a market:// link to your app.
If the user follows the link to the Market, it will detect if the app is already loaded on your phone and will prompt you to either Install it or Open it....which is the behavior you are asking for. I also don't understand how the user can try to 'launch your app if it is not installed' - if it's not installed he won't be able to see it let alone launch it, so he's not going to get any 'ugly error'. Of course, if what you are really trying to do is get your web page to launch an app on my phone when I visit it then.........please give me the address of your web page so I know never to go there. :-) On Jan 14, 2:10 pm, ls02 <agal...@audible.com> wrote: > The app is launched from the web page to perform certain action.
