Android : Add A New ContentProvider To Contacts

I want to add an extra field to the phonebook on android. The field contains a new contact method and when clicked it should start my own application/intent. I have created my own content provider that stores the information. I want to add this contentProvider to the phonebook in the same way organizations and email are added to the phone book. So how do i do this? I tried adding a new contact method but the field KIND needs an integer input which seems to be predefined to some specific methods (EMAIL, IM, ADDRESS etc)

So do i need to add a new type of KIND or can I link my contentProvider to the phone book so that it shows up as an extra field in the phone book?
