I've develop a Live Wallpaper that was working perfectly in Android 2.1. It emulate the standard Android wallpaper by having a bitmap scrolling when a user changes screen.
To achieve that effect I use the event "
onOffsetsChanged" to detect screen changes when the user swipes left and right.
I just installed Android 2.2.1 and now the values returned in onOffsetsChanged for xPixelOffset and yPixelOffset are always 0. The value for xOffset and yOffset do return values from 0 to 1 but because WallpaperManager.getInstance(myContext).getDesiredMinimumHeight() and WallpaperManager.getInstance(myContext).getDesiredMinimumHeight() now return the screen physical size instead of the screen virtual size, I have now way to calculate how much that percentage represent in terms of actual displacement.
I know it's possible to achieve the desired result because the packed wallpaper has that behaviour.
Can somebody help? Is this a problem with Samsung Galaxy S implementation or is this a standard behaviour?

When developing a live wallpaper how can I get the virtual screen size? How can I know in which virtual screen the user is in?
