If you want to interact with a specific component of yours, you can use a broadcast (or a service etc) to interact with it. If you want to interact with the current wallpaper, you can find out what component it is with getWallpaperInfo(). You could even do stuff like define a meta-data name under which your wallpaper component specifies the broadcast receiver you should send broadcasts to. If you want to do this with one of your live wallpapers even when it currently isn't selected, than of course you can't use the facilities that revolve around the current wallpaper, but can just come up with whatever approach you want (receiver, service, etc) for your two apps to interact. -- Dianne Hackborn Android framework engineer [email protected] Note: please don't send private questions to me, as I don't have time to provide private support, and so won't reply to such e-mails.
