            </intent-filter>
            <meta-data 
                android:name="android.service.wallpaper" 
                android:resource="@xml/wallpaper" />
        </service>
    </application>

</manifest> 

我不知道这个错误是什么意思。我希望有人可以帮助我在这里运行这个东西..谢谢..

您的错误是 ClassNotFoundException，它与您的动态壁纸有关(org.anddev.wallpaper.live.cigarette)。所以我猜您的动态壁纸声明manifest 中的内容不正确(例如，它可能不在应用程序标签中，...)
您可以在以下页面的 list 中查看有关在 list 中声明服务的更多详细信息:
developer.android.com/guide/components/services.html
developer.android.com/reference/android/app/Service.html

编辑:
我看到了你的 list 。你的项目似乎没有 Main/Launcher Activity。如果你的项目没有 Main/Launcher Activity，你的服务就无法注册，所以当你尝试使用它们时，你获取 ClassNotFoundException。
还要确保服务的完全限定类名称是 android.service.wallpaper.WallpaperService。
