When the system emits an Intent for which you have multiple apps that can handle the intent, a dialog opens to tell you which application you want to use with that intent.
Is there a way to see what these associations are, and clear them?
If there is no app or interface to do that, do you know of an API to access these associations?
EDIT: When I said associations, I was thiking of the "late-bound" associations. For example, when I open a link and I have multiple browsers, an intent is fired saying "view link", and I choose "always use that application"; what can I do if, after some time, I would prefer to use another application for that intent?
