A Handler is associated with a Looper, not an activity. Anyone can make a Handler for the main thread, and post messages to it, and they will be processed. What happens to activities on that thread has no impact on handlers.
Another way to look at it -- you don't pass an Activity to a Handler when creating the Handler, so there is no association a Handler has with any Activity. (The Looper us implicitly known because there is a 1:1 relationship between a running thread and a Looper. There is no such relationship with an Activity.)
