</manifest> 

I Dont have any idea what this error means. I hope someone can help me here to run this thing.. Thank You..

Answer 1

Your error is ClassNotFoundException and it is in about your live wallpaper(org.anddev.wallpaper.live.cigarette).So I guess that your declaration of live wallpaper in manifest is incorrect(for example it may be not in application tag,…)
You can see more details in about declaring a service in the manifest in these pages:
developer.android.com/guide/components/services.html
developer.android.com/reference/android/app/Service.html

Edit:
I saw your manifest.It seems that your project has no Main/Launcher Activity.If your project has no Main/Launcher Activity,your services can not be registered and so when you try to use them,you get ClassNotFoundException.
Also be sure that fully qualified class name of service is android.service.wallpaper.WallpaperService.
