How do I find Activity Class?

[Se7enLC]

I may have the terminology all wrong, but how do I find out what options an app has for starting?

For example, the Browser has BrowserActivity to start a new window.

Is there a way to list all the available activities of an app? Or is there a published list somewhere?

If you open the apk in Astro then click on details you can see all of the activities.
