Thanks Mark and Diane for the help. My task is to properly place my living wallpaper background (I use the current "dead" wallpaper) behind the system's placement of icons and widgets. My users should be able to do "Settings" on different (right, center, left) home screens.
Here's the three assumptions that, so far, work for me: 1. Upon exit from preview mode the system will always show the panel of icons and widgets last showing before preview mode. In WallpaperService.onCreate() I get wallpaper width from WallpaperManager.getDrawable() and getBitmap() and getWidth(), and 2. device screen width in pixels = wallpaper width / 2; However many homescreens there are, 3. offset to center panel of wallpaper = the negative of (device screen width / 2); Therefore, during preview mode I show this center panel. Upon exit from preview mode I get my first onOffsetsChanged() callback and can calculate the real number of home screens and manage my background accordingly. Perhaps in the future some live wallpaper applications would be better served if the system exposed additional information it obviously has: (a) during onCreate(), some direct way to get device screen size and number of home screens, (b) upon entry to preview mode, some way to get which home screen was last showing (c) upon exit from preview mode, some way to set which home screen (of icons and widgets) will show next. And, by the way, some documentation about the usefulness of onOffsetsChanged()-s with xSteps of 0.0 and -1.0. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
