[android-developers] Re: Forward search queries to one single activity that handles search

Take a look at the SearchManager stuff:
http://developer.android.com/reference/android/app/SearchManager.html

From what I can see you only want one activity that responds to the
search, the others need to be able to initiate (I think) what would be
a 'local search'
When you start a search the system it always going to create an
instance of those classes which have the filter so they can process
they search intent.
