How to delete a contact?

Question

I'm working at android 2.1 ContactContract, when I had not set account(for example: gmail account) to android emulator then, new a contact, but could not delete this contact at DB.

ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
    String[] args = new String[] {id};
    ops.add(ContentProviderOperation.newDelete(Data.CONTENT_URI)
            .withSelection(Data.CONTACT_ID + "=?", args)
            .build());
    ops.add(ContentProviderOperation.newDelete(RawContacts.CONTENT_URI)
             .withSelection(RawContacts.CONTACT_ID + "=?", args)
             .build());
    ops.add(ContentProviderOperation.newDelete(Contacts.CONTENT_URI)
             .withSelection(Contacts._ID + "=?", args)
             .build());

Deleting the contact from RawContacts will delete the data from Data, Contacts table.

ArrayList ops = new ArrayList(); String[] args = new String[] {id}; 
// if id is raw contact id
ops.add(ContentProviderOperation.newDelete(RawContacts.CONTENT_URI).withSelection(RawContacts._ID + "=?", args) .build()); 
    OR
// if id is contact id
ops.add(ContentProviderOperation.newDelete(RawContacts.CONTENT_URI).withSelection(RawContacts.CONTACT_ID + "=?", args) .build());
getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
