I hear that "some Activities never display UIs" according to http://code.google.com/android/devel/building-blocks.html. My question: is this true?
I have yet to find a way to make an Activity without a UI. Documentation suggests an Activity can be non-visual. For example, Activity.getWindow() returns the "current window, or null if the activity is not visual." When would an Activity have a null Window? The docs say "the Activity class takes care of creating a window for you..." at http://code.google.com/android/reference/android/app/Activity.html. Any idea? Ron PS - Yes, I know a Service does not have a UI. My question is about the Activity class. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
