Common Intent filter for multiple activities

I have activity A and activity B which require me to call the Flickr Authentication for 2 different purposes. Currently, the I have the Intent-Filters defined separately for both the activities, but this results in two different apps (separate icons on the homescreen) to the user when the intent-filter is invoked.

I would like to know how a single intent filter can be defined for multiple activities(A and B), at the same the time the onResume() of the forground activity should be invoked on return from the Intent.
