The below code solved my problem :)

    String selection = ContactsContract.RawContacts._ID+ "=?";
    String selectionargs[] = { String.valueOf(rawContactId) }; //Get rawContactId    

    int deletedRawContacts = context.getContentResolver().delete(ContactsContract.RawContacts.CONTENT_URI.buildUpon()
                                .appendQueryParameter(ContactsContract.RawContacts.ACCOUNT_NAME, ACCOUNT_NAME)
                                .appendQueryParameter(ContactsContract.RawContacts.ACCOUNT_TYPE, ACCOUNT_TYPE)
                                .appendQueryParameter(ContactsContract.CALLER_IS_SYNCADAPTER, "true").build(),
                                 selection,selectionargs);
    System.out.println("No. of contacts deleted are " + deletedRawContacts);

Note: You should modify RawContacts, not Contacts. Contacts are simply joined RawContacts, and RawContacts are created on an account.

Not sure it's possible, since RawContacts need to belong to exactly one account. You can try looping over those RawContacts, and change the values at account_type and account_name to some other valid and existing account.

it has a chance of succeeding, but I'm not sure you can count on it for all Android versions / devices.
