What's the most native way to connect android app to a webserver?

I'm new to android developing but 开发者_JAVA技巧I have an app in mind, that needs to be connected to a Webserver (implemented as a java servlet if it makes a difference) in order to receive data (both real-time ajax-like and not real-time). What's the best way to perform such communication in the android interfaces ?

Thanks In Advance, Chris

Just use a HttpClient.
