Answer 1

This is working for me to get contact with phone number. Here we are querying Data table, and using CONTACT_ID contact provider documentation

    @Override
    public Loader onCreateLoader(int id, Bundle args) {

final String ORDER_BY = ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME_PRIMARY + " ASC";

    final String[] PROJECTION = {
            ContactsContract.CommonDataKinds.Phone.CONTACT_ID,
            ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME_PRIMARY,
            ContactsContract.CommonDataKinds.Phone.NUMBER
    };

return new CursorLoader(
                context,
                ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                PROJECTION,
                null,
                null,
                ORDER_BY
        );
}
