android live wallpaper rescaling http://stackoverflow.com/questions/5208203/android-live-wallpaper-rescaling so I can get this going. I tired a few things figured I would make a scaler for everything example int scaler then in onSurfaceChanged scaler width 1024 if the bigger image is 1024. that will give me a ratio to work with everywhere. then scale accordingly.. this question Well um all I can say is Welcome to the real world. You get your screen dimensions passed to you via onSurfaceChanged and yes it is your job to figure out how to scale everything based on this data. That's why they pay us the big bucks. You.. single engine class so our methods can share data via private variables. For example in the Cube wallpaper in the SDK onSurfaceChanged sets mCenterX for later use in drawCube . I suggest beginning with a similar simple approach. Handling scrolling takes some..
