Google Checkout in Android

I am sending an xml request to google checkout and getting the xml response too.

The request that i m sending is

StringBuffer buf = new StringBuffer();

buf.append("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");

buf.append("<checkout-shopping-cart xmlns=\"http://checkout.google.com/schema/2\">");

buf.append("<shopping-cart>");

buf.append("<items>");

buf.appen开发者_StackOverflow社区d("<item>");

buf.append("<item-name>Ville</item-name>");
buf.append("<item-description>BabbleVille</item-description>");
buf.append("<unit-price currency=\"USD\">12</unit-price>");
buf.append("<quantity>1</quantity>");
buf.append("</item>");
buf.append("</items>");
buf.append("</shopping-cart>");
buf.append("<checkout-flow-support>");
buf.append("<merchant-checkout-flow-support>");
buf.append("<shipping-methods>");
buf.append("<flat-rate-shipping name=\"SuperShip Ground\">");
buf.append("<price currency=\"USD\">9.99</price>");
buf.append("</flat-rate-shipping>");
buf.append("</shipping-methods>");
buf.append("</merchant-checkout-flow-support>");
buf.append("</checkout-flow-support>");
buf.append("</checkout-shopping-cart>");

The response that I am getting is

<?xml version="1.0" encoding="UTF-8"?>
<checkout-redirect xmlns="http://checkout.google.com/schema/2" serial-number="4f6d85ac-0e83-41f1-81ef-60e86bd07b9d">

<redirect-url>https://sandbox.google.com/checkout/view/buy?o=shoppingcart&amp;shoppingcart=602624134680807</redirect-url>

</checkout-redirect>

Now, I dont know what to do with this response. I am very new to Google Checkout. The redirect url that i get if opened in browser then shows error. How will the buyer be redirected to enter his google account.

Can someone please let me know how to proceed with this response?

I think this might help you. Google Checkout

** UPDATE **

Google Checkout has been deprecated. Now Google encourages you to use Google Wallet.
