Ok, after a bit digging, here is what i found. Take the answer about auto complete TextView, add to it the following and you get what i was looking for.

Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null); 
    while (cursor.moveToNext()) { 
        String contactId = cursor.getString(cursor.getColumnIndex( 
                ContactsContract.Contacts._ID)); 
        String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)); 
        if (Boolean.parseBoolean(hasPhone)) { 
            // You know it has a number so now query it like this
            Cursor phones = getContentResolver().query( ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId, null, null); 
            while (phones.moveToNext()) { 
                String phoneNumber = phones.getString(phones.getColumnIndex( ContactsContract.CommonDataKinds.Phone.NUMBER));                 
            } 
            phones.close(); 
        }

        Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId, null, null); 
        while (emails.moveToNext()) { 
            // This would allow you get several email addresses 
            String emailAddress = emails.getString( 
                    emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
        } 
        emails.close(); 
    }
    cursor.close();
