Jesus Images Download [EXCLUSIVE] Wallpaper
Eloy Mertz
Android has a way to set the home screen wallpaper. The user taps "menu" and then selects "wallpaper" to set a wallpaper from the system. The resulting wallpaper image is properly scaled in both portrait and landscape mode.
I looked for tutorials and examples on how to set a wallpaper like they do, but couldn't find out how to do it. Can you show me a code sample showing me the secret to this so the resulting wallpaper is scaled correctly?
I was just looking at this. While you can observe actual file sizes from wallpaper images in the Launcher .apk, a better way is to query the WallpaperManager for the desired size (which is independent of orientation).
At this point, I create a new bitmap of the exact required size and write my own bitmap into it. The tricky part is calculating padding and scaling, as well as accounting for the status bar. However, once you write this properly-sized image as a wallpaper, it should work exactly like a system wallpaper.
