A URI that can be used to retrieve the contact's full-size photo. If PHOTO_FILE_ID is not null, this will be populated with a URI based off Android.Provider.ContactsContract.DisplayPhoto.ContentUri. Otherwise, this will be populated with the same value as Android.Provider.ContactsContract.ContactsColumns.PhotoThumbnailUri. A photo can be referred to either by a URI (this field) or by ID (see Android.Provider.ContactsContract.ContactsColumns.PhotoId). If either PHOTO_FILE_ID or PHOTO_ID is not null, PHOTO_URI and PHOTO_THUMBNAIL_URI shall not be null (but not necessarily vice versa). Thus using PHOTO_URI is a more robust method of retrieving contact photos.
