you want to retrieve the number of new contacts since when?

if you adding contacts with your app then just get the number of contacts before you add any and save that value. then after the user has added contacts get the number again and find the difference between the previous number of contacts. that will be the number of new contacts, but the best way to do it would just be to keep an internal counter of when the user adds contacts.

Just make this change to your cursor query

     Cursor cursor = getActivity().getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, "_id DESC");
