Honest question: how is the new paradigm of "activities" different from e.g. Android "activities" (which even have the same name)?

Well that's just it. They're not "new", Activities have been a KDE feature since before the 4.0 release in Jan. 2008 (some months before the first Android phone was released in Oct. 2008).

Either way, my very limited understanding of the Android SDK when I reviewed it some months ago was that an activity was an implementation detail for a software developer, not a user-visible term in the Android UI.

I am no expert, but the Wikipedia says that Google published their Android platform on November 2007. The SDK was available then even if the first phones would not come out for almost a year. (Remember the "OpenHandsetAlliance" that appeared as a response to Apple's iPhone?)

So I understand that activities in KDE are an element of the UI, thanks. Intriguing. dtlin's post below and the link posted are a very good source.

You're right that the Android SDK was available early, just keep in mind Plasma was actively in development before the KDE 4.0 release as well. ;)

I'm too lazy to dig up links (and besides, doesn't really matter). Feels like the OpenHandsetAlliance was so long ago though, amazing how much has changed just in 4 years...

They're not alike at all.

Plasma activities are like super-virtual desktops: they are a collection of desktop state, configuration, and windows.

Android is easier to explain by analogy. The whole system is a web browser and an activity is a specific web page. One program may have many activities, just as one host may have many web pages, but while you can navigate between them freely, you can only see one at once.
