## cl.bundlemanager.1 Field Change of the ApplicationInfo Structure in API Version 9
The **ApplicationInfo** structure [[bundleManager/applicationInfo.d.ts](https://gitee.com/openharmony/interface_sdk-js/blob/master/api/bundleManager/applicationInfo.d.ts)] in API version 9 has field changes, with the **systemApp** field being added and the **entryDir** field being deleted.
**Change Impacts**
There is no impact on applications that use the APIs of versions earlier than 9. The applications that use the APIs of version 9 need to adapt new modules and APIs.
**Key API/Component Changes**
The following table describes the changed fields in the **ApplicationInfo** structure.
| Deleted Field | Added or Changed Field in API Version 9| Type |
| -------- | -------------- | ------- |
| None | systemApp | boolean |
| entryDir | None | string |
**Adaptation Guide**
Import the bundle manager query module and use the **systemApp** field in the **ApplicationInfo** structure of API version 9. If the **entryDir** field is used, change the field because it is redundant in features where HAP decompression is not required.

**Adaptation Guide**<br>
Import the **backgroundTaskManager** module.
```
import bundle form '@ohos.resourceschedule.backgroundTaskManager'
```
Exception handling also needs to be adapted. For details, see the [backgroundTaskManager API reference](../../../application-dev/reference/apis/js-apis-resourceschedule-backgroundTaskManager.md).
## c2.resourceschedule.usageStatistics
Rectified original APIs of **deviceUsageStatistics** of the resource scheduler subsystem. All APIs in API version 8 and earlier versions are deprecated, and original APIs in API version 9 are deleted. New APIs in API version 9 need to be used. The new APIs in API version 9 comply with the error code specifications.
**Change Impacts**
The application developed based on the SDK versions of OpenHarmony 3.2.8.2 and later needs to adapt the modules and APIs in API version 9 and their methods for returning API error information. Otherwise, the original service logic will be affected.
**Key API/Component Changes**
The following methods, attributes, enumerations, and constants are changed in API version 9 and later versions. The **@ohos.bundleState.d.ts** file is deprecated, the **@ohos.resourceschedule.usageStatistics.d.ts** file is added, and the class name is changed from **bundleState** to **usageStatistics**.

The application developed based on the SDK versions of OpenHarmony 3.2.8.2 and later needs to adapt the modules and APIs in API version 9 and their methods for returning API error information. Otherwise, the original service logic will be affected.
**Key API/Component Changes**
The following methods, attributes, enumerations, and constants are changed in API version 9 and later versions. The **@ohos.reminderAgent.d.ts** file is deprecated, the **@ohos.reminderAgentManager.d.ts** file is added, and the class name is changed from **reminderAgent** to **reminderAgentManager**.

**Adaptation Guide**<br>
Import the **reminderAgentManager** module.
```
import bundle form '@ohos.reminderAgentManager'
```
Exception handling also needs to be adapted. For details, see the [reminderAgentManager API reference](../../../application-dev/reference/apis/js-apis-reminderAgentManager.md).
System application verification is not performed for system APIs provided by the ability when they are called. The APIs can be used by a third-party application using the full SDK, which brings security risks. Therefore, application identity verification is added to OpenHarmony 4.0.2.1 and later versions.
**Change Impacts**
System APIs are available to only system applications. When a third-party application tries to use a system API, the **202** error will be returned via either an exception or asynchronous callback.
Added the [AVPlayer](../../../application-dev/reference/apis/js-apis-media.md#avplayer9)<sup>9+</sup> API for audio and video playback, with the updated state machine and error codes, which is recommended. The following APIs for audio playback and video playback are no longer maintained: [AudioPlayer](../../../application-dev/reference/apis/js-apis-media.md#audioplayer)<sup>6+</sup> and [VideoPlayer](../../../application-dev/reference/apis/js-apis-media.md#videoplayer)<sup>8+</sup>.
**Change Impacts**
The original APIs can still be used but are no longer maintained. You are advised to use the new API instead.
For details, see the [reference](../../../application-dev/reference/apis/js-apis-media.md) for each API.
## cl.media.2 API Change of the Recording Function
Added the [AVRecorder](../../../application-dev/reference/apis/js-apis-media.md#avrecorder9)<sup>9+</sup> API for audio and video recording, with the updated state machine and error codes, which is recommended. The following APIs for audio recording and video recording are no longer maintained: [AudioRecorder](../../../application-dev/reference/apis/js-apis-media.md#audiorecorder)<sup>6+</sup> and [VideoRecorder](../../../application-dev/reference/apis/js-apis-media.md#videorecorder9)<sup>9+</sup>.
The [AudioSourceType](../../../application-dev/reference/apis/js-apis-media.md#audiosourcetype9) and [VideoSourceType](../../../application-dev/reference/apis/js-apis-media.md#videosourcetype9) APIs shared by the old and new recording APIs are changed to non-system APIs.
**Change Impacts**
The [AudioRecorder](../../../application-dev/reference/apis/js-apis-media.md#audiorecorder)<sup>6+</sup> and [VideoRecorder](../../../application-dev/reference/apis/js-apis-media.md#videorecorder9)<sup>9+</sup> APIs can still be used but are no longer maintained. You are advised to use the [AVRecorder](../../../application-dev/reference/apis/js-apis-media.md#avrecorder9)<sup>9+</sup> API instead.
For details, see the [reference](../../../application-dev/reference/apis/js-apis-media.md) for each API.
## cl.media.3 Error Code Change
Added the standard error code enumeration type [AVErrorCode9](../../../application-dev/reference/apis/js-apis-media.md#averrorcode)<sup>9+</sup> that replaces the original error code enumeration type [MediaErrorCode](../../../application-dev/reference/apis/js-apis-media.md#mediaerrorcode)<sup>8+</sup>.
**Change Impacts**
The error code enumeration type [MediaErrorCode](../../../application-dev/reference/apis/js-apis-media.md#mediaerrorcode)<sup>8+</sup> is still used for original APIs. [AVErrorCode9](../../../application-dev/reference/apis/js-apis-media.md#averrorcode)<sup>9+</sup> is used for newly added APIs.
