android Programming Glossary: xpixels

http://stackoverflow.com/questions/5208203/android-live-wallpaper-rescaling

5 screens i.e. xOffset 0 0.25 0.5 0.75 or 1 but it can be any value from 0 to 1 0.5 would indicate 3 screens. xPixels gives you an indication of how much the launcher wants you to shift your imagery based on the screen you're on normally.. minimum width of the wallpaper desired by the launcher so you can explicitly understand the virtualization implicit in xPixels. For example in my engine constructor I have mContext getApplicationContext mWM WallpaperManager.getInstance mContext mDW.. mContext mDW mWM.getDesiredMinimumWidth My device has 320 pixel width I get mDW 640 as I scroll from screen to screen xPixels changes by 80 each time...because four scrolls across five screens is supposed to double the amount of revealed artwork..
