Is there a way to update an already installed application on Android?
How can I provide a bug fix for my application?
Is there some sort of built-in
general purpose application update mechanism in Android which will change only
part of my code without need to download whole application and install it again?
Something like Java Web Start, where only changed jars are updated.

Yes. This is built into the APK installer system. However, it is up to you to get the APK (Android application package) to the device, either through a market (e.g., Android Market) or through your Web site.

However, one thing you should note is that application upgrades are allowed only if the same key is used to sign the APK - otherwise you need to distribute the "update" as a different application.
