Get information from website for Android

I want to make an application that compare pizza prices. To do that I have to go to the actual sit开发者_C百科e and enter and search. How can I display the prices WITHOUT the user seeing the actions of going to the website and entering a search. Would I use a WebView and a WebViewClient?

You would use HttpClient to do the web calls in the background. You would only use WebView to display webpages to the user.
