Embed URL in QR Code

How do I embed an URL in a QR开发者_StackOverflow code using Zxing, so that the barcode scanner can detect it as an URL?

I think I need to add something more than just the http://.

The most common application of barcodes is to encode the text of URL such as http://google.com/m. To do so, simply encode exactly the text of the URL in the barcode: "http://google.com/m". Include the protocol ("http://", here) to ensure it is recognized as a URL.

Readers should open the URL in the device's web browser when decoding a URL. It is probably desirable for a reader to display the URL and ask the user whether to proceed, so that the user may see the URL before accessing it.

Erm, you just write the URL in the QR code. The content is just "http://google.com" or whatever. Any reader will recognize it.
