    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <service 
            android:name="LiveWallpaperService"
            android:enabled="true"
            android:icon="@drawable/icon"
            android:label="@string/service_name"

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

</manifest> 

我不知道这个错误意味着什么.我希望有人可以帮我在这里运行这件事..谢谢..

你的错误是ClassNotFoundException,它是关于你的动态壁纸(org.anddev.wallpaper.live.cigarette).所以我猜你的动态壁纸声明manifest是不正确的(例如它可能不在应用程序标签,...)
你可以看到有关声明更多细节这些页面中的清单中的服务:
developer.android.com/guide/components/services.html
developer.android.com/reference/android/app/Service.html

编辑:
我看到你的清单.似乎你的项目没有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,你就得到了ClassNotFoundException.
还要确保完全限定的服务类名称android.service.wallpaper.WallpaperService.
