 ## 开发步骤
 
-### 基于FA模型
-
-基于FA的Service Ability使用，参考[ServiceAbility开发指导](../application-models/serviceability-overview.md)。
-
-当不需要与后台执行的长时任务交互时，可以采用startAbility()方法启动Service Ability。并在Service Ability的onStart回调方法中，调用长时任务的申请接口，声明此服务需要在后台长时运行。当任务执行完，再调用长时任务取消接口，及时释放资源。
-
-当需要与后台执行的长时任务交互时（如播放音乐等）。可以采用connectAbility()方法启动并连接Service Ability。在获取到服务的代理对象后，与服务进行通信，控制长时任务的申请和取消。
-
-1、新建Api Version 8的工程后，在工程目录中右键选择“new” -> “Ability” -> “Service Ability” 快速创建Service Ability组件。并在config.json文件中配置长时任务权限ohos.permission.KEEP_BACKGROUND_RUNNING、后台模式类型，其中Ability类型为“service”。
