Most communication Apps have their own contacts.  The information in their contacts database are very similar.  Basically, the user need only one copy of them.  They don't want to maintain multiple copy of contacts.  So, the user will keep all contacts in the database of Contacts API and forget contacts of communication Apps.  But, communication Apps still maintain their-owned contacts for showing status of friends or for other purposes. So, the idea is to borrow the experience of mobile phone.  When you ask your friend for phone number, you will call it at first to make sure the number is correct.  Then, you create a new contact from call history.  You select the number of your friend from call history and the phone will ask you what do you want to do.  You ask the phone to add the phone number to contacts, then you pick up an existing contact or create a new one.  The idea is to wake up Contacts App to handle the new friend account/address/or number when adding a new friend in a communication App.  That is saying, when the user add a friend in Skype, Skype will wake up Contacts App and tell it to record that account.  Then Contact App will ask the user if he want to create a new contacts or add the account/address/or number to an existing contacts.
