This method can return null when: <ul> <li>Colors are still being processed by the system.</li> <li>The user has chosen to use a live wallpaper: live wallpapers might not implement android.service.wallpaper.WallpaperService.Engine#onComputeColors() WallpaperService.Engine#onComputeColors().</li> </ul>
