ContentResolver cr = getContentResolver();
        Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
            null, null, null);
        if (cursor.moveToFirst()) {
            String contactId =
                cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
            //
            //  Get all phone numbers.
            //
            Cursor phones = cr.query(Phone.CONTENT_URI, null,
                Phone.CONTACT_ID + " = " + contactId, null, null);

                String number = phones.getString(phones.getColumnIndex(Phone.NUMBER));
                int type = phones.getInt(phones.getColumnIndex(Phone.TYPE));
