[android-developers] Idiomatic way of getting count of items in content provider directory

For both writing a content provider, and using an existing one, what
is the preferred way of getting the number of items in a directory?

For example
content://foo/bar

I would like to know how many items are in bar. I could select all of
the rows and then call Cursor.getCount() but that seems terrible.

If I am writing my own Content Provider, I suppose I could add a Uri
in my content provider like

content://foo/bar/count

which return a ResultSet containing select(*) from bar, essentially.

Thanks
