I'm trying to aggregate two `Contacts` using their `Contacts._ID` using
code from the `Android Contacts` application. I have sorted out many most
problems but `RawContacts.NAME_VERIFIED` is not in the `public API`. Could
you suggest any method to fix this without losing functionality? Also it
would be nice if you can point out any mistakes that I might have made. I
have posted the full code below.
