I have yet to encounter an app with a hundred activities. And if your app has a hundred activities you're doing something wrong and probably have a problem with usability not discoverability. And even if you have a hundred activities and the user can't remember which ones have a menu, it takes about 1 second to press the menu button to determine if there is one or not. Compare that with implementing a visual cue for a hundred activities and making them all fit the UI. Good luck with that. > If the presentation of icons that don't do anything is trivially handled > by one time learning experiences, perhaps the application launcher > should not bother to remove the icons of deleted applications. :*) > 1) You got it backwards - it's the NON-EXISTENCE of icons that would otherwise trigger the menu to show that is the one-time learning curve. IOW, without any visual cue, it takes ONE TIME to learn that the menu exists. With a visual cue I learn the menu exists and render the visual cue utterly useless thereafter. 2) Your example of not removing deleted icons is, again, backwards. By not deleting icons you would be telling the user that functionality that does not exists actually does, which is nonsensical and NOT the same as not showing an icon for functionality that does exists and is accessible via other means. ------------------------------------------------------------------------------------------------- TreKing - Chicago transit tracking app for Android-powered devices http://sites.google.com/site/rezmobileapps/treking -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
