android - How can you detect if an Intent was not launched due to multiple possible targets?

Question

If I launch an Intent via activity.startActivity(intent) and there are multiple apps which can handle the Intent, you get a dialog along the lines of "Complete action using:" followed by the list of apps.

How can I detect if they cancel this dialog (e.g. via the back button) back to the app, rather than select an option?
