Correct. Which is why this is where you display the generic market URL, even if they're on their phones and have you app installed (which you can't know, as we've established). > Say you have a Web page that uses Flash.

In your example the Flash app runs in the browser, which is where the Flash plug-in will be. In Android it's fairly trivial to detect if another app is installed. However, trying to dynamically discover what may or may not be running in a completely different, unrelated environment without any "hooks" on both ends is not so trivial. ------------------------------------------------------------------------------------------------- TreKing <http://sites.google.com/site/rezmobileapps/treking> - Chicago transit tracking app for Android-powered devices -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
