Answer 1

Code goes in functions.php file of your active child theme (or theme) or also in any plugin file. This code is tested and works.

All payment methods are only available on Checkout page.

add_action('woocommerce_cart_calculate_fees','custom_handling_fee',10,1);
function custom_handling_fee($cart){
    if(is_admin() && ! defined('DOING_AJAX'))
        return;
    if('cod' === WC()->session->get('chosen_payment_method')){
        $extra_cost = 0.015;
        $cart_total = $cart->cart_contents_total; 
        $fee = $cart_total * $extra_cost;
        if($fee != 0)
        $cart->add_fee('COD Charge',$fee,true);
    }
}

You will need the following to refresh checkout on payment method change, to get it work:

add_action( 'wp_footer','custom_checkout_jqscript');
function custom_checkout_jqscript(){
    if(is_checkout() && ! is_wc_endpoint_url()):
    ?>
    <script type="text/javascript">
    jQuery( function($){
        $('form.checkout').on('change', 'input[name="payment_method"]', function(){
            $(document.body).trigger('update_checkout');
        });
    });
    </script>
    <?php
    endif;
}
