> **说明：**
> - 从API Version 9 开始，该接口不再维护，推荐使用新接口[@ohos.resourceschedule.backgroundTaskManager (后台任务管理)](js-apis-resourceschedule-backgroundTaskManager.md)
> - 本模块首批接口从API version 7开始支持。后续版本的新增接口，采用上角标单独标记接口的起始版本。从API version 9开始，导入模块由@ohos.backgroundTaskManager迁移至@ohos.resourceschedule.backgroundTaskManager
-> - 后台任务管理错误码见[backgroundTaskManager错误码](../errorcodes/errorcode-backgroundTaskMgr.md)。
