Problem
I am working on my own home launcher replacement and it works fine but one thing bothers me. When I press a home key, current home activity (the one defined in manifest as main/defualt/launcher/home) restarts - current activity instance onpause is executed and oncreate is fired again, so new activity is brought up. On the other hand, ADW launcher and LauncherPRo does not behave like that - I do not a refresh like in my case. Launcher Pro even can do several actions: - If you are on the main screen with app icons, it zooms out to see a snapshot of all screens, - If you open a drawer and press Home, it just go back to the main screen. Any ideas how to do that? I just did a very simple prototype from scratch with just one activity (defined in manifest as main/defualt/launcher/home) and I see the same thing - it gets recreated if I press Home.
