I have found a intent that will start Google search with a query but that will not yield the same results as actually "saying" "call" in Google now. Here is the tasker intent.
Www (588)
A1: [X] Send Intent [ Action:com.google.android.googlequicksearchbox.GOOGLE_SEARCH Cat:Default Mime Type: Data: Extra:type:Voice Extra:query:Ok Google call Package: Class: Target:Activity Continue Task After Error:On ]
Any help would be greatly appreciated..
Thanks, Rich..
