Yes, I am familiar with that mechanism. However, that is not like the event/eventhandler mechanism that is available in javascript/gwt. In the asynctask mechanism, the asynctask#postExecute runs on the UI thread and the asynctask needs to passed in a view if a specific view needs to be updated. however, in the javascript mechanism of event/eventhandler, the component that fires the event does not need to know anything about who is going to receive that event. So, it allows for a bit of modular design (clean separation of functionality/view logic/data model). The async task mechanism is, like you said, a multi-threading mechanism in android, however, the event/eventhandler model is more akin to javascript's event model or akin to the JMS publish/subscribe model in JEE. I can see how the async task mechanism can be used in lieu of the event/eventhandler mechanism, but thats not apples to apples. make sense?
