3## cl.resourceschedule.backgroundTaskManager
4Rectified the original APIs of **backgroundTaskManager** of the resource scheduler subsystem. All APIs of API version 9 in the **@ohos.backgroundTaskManager.d.ts** file are deleted, and the APIs of API version 9 in the **@ohos.resourceschedule.backgroundTaskManager.d.ts** file are used. The new APIs in API version 9 comply with the error code specifications.

6**Change Impacts**
7
8If your application is developed based on the SDK versions of OpenHarmony 3.2.10.5 and later, adapt to the modules and APIs in API version 9 and the pattern for returning error codes. Otherwise, the service logic will be affected.
