# Ability Subsystem Changelog

Compared with OpenHarmony 3.2 Beta4, OpenHarmony 3.2.10.1(MR) has the following API changes in the ability subsystem:

## cl.ability.1 API Migration
The **requestPermissionsFromUser** API of **UIAbilityContext** is migrated from the ability subsystem to the security subsystem.

Previously, the permission popup was implemented based on **UIAbility**, which used the **startAbilityForResult** API of **UIAbilityContext** to return the permission authorization result to the caller. Therefore, **requestPermissionsFromUser** was temporarily placed in **UIAbilityContext**. The permission popup is now implemented based on **ServiceExtensionAbility**, which no longer requires **startAbilityForResult** of **UIAbilityContext**. Therefore, **requestPermissionsFromUser** is migrated to the security subsystem.

You need to adapt your application.

**Change Impact**

JS APIs in API version 9 are affected. Your application needs to adapt these APIs so that it can properly implement features in the SDK environment of the new version.

**Key API/Component Changes**

| Module                   | Class               | Method/Attribute/Enum/Constant                                         | Change Type|
| ------------------------- | ------------------- | ------------------------------------------------------------ | -------- |
| application/UIAbilityContext        | UIAbilityContext        | requestPermissionsFromUser(permissions: Array<string>, requestCallback: AsyncCallback<PermissionRequestResult>): void; | Deleted    |
| application/UIAbilityContext        | UIAbilityContext        | requestPermissionsFromUser(permissions: Array<string>): Promise<PermissionRequestResult>; | Deleted    |
| @ohos.abilityAccessCtrl        | AtManager         | requestPermissionsFromUser(context: Context, permissions: Array<Permissions>, requestCallback: AsyncCallback<PermissionRequestResult>) : void; | Added    |
| @ohos.abilityAccessCtrl        | AtManager         | requestPermissionsFromUser(context: Context, permissions: Array<Permissions>) : Promise<PermissionRequestResult>; | Added    |


**Adaptation Guide**

The following illustrates how **requestPermissionsFromUser** is called to show a permission popup.

Stage model:

```ts
import abilityAccessCtrl from '@ohos.abilityAccessCtrl.d.ts';
// onWindowStageCreate lifecycle of UIAbility.
onWindowStageCreate() {
    let AtManager = abilityAccessCtrl.createAtManager();
    // requestPermissionsFromUser determines whether to display a popup based on the permission authorization status.
    AtManager.requestPermissionsFromUser(this.context, ["ohos.permission.MANAGE_DISPOSED_APP_STATUS"]).then((data) => {
        console.log("data type:" + typeof(data));
        console.log("data:" + data);
        console.log("data permissions:" + data.permissions);
        console.log("data result:" + data.authResults);
    }).catch((err) => {
        console.error('Failed to start ability', err.code);
    })
}
```



## cl.ability.2 Deletion of Deprecated APIs in API Version 9

In the [Ability Exception Rectification](../OpenHarmony_3.2.8.3/changelogs-ability.md) document, some APIs in API version 9 have been marked as deprecated. According to API specifications of OpenHarmony, these APIs should be deleted.

**Change Impact**

The application developed based on earlier versions needs to use new APIs to replace the deleted ones. Otherwise, the application compilation will be affected.

**Key API/Component Changes**

API files are deleted.

**Adaptation Guide**

As mentioned above, only several APIs have their names changed in terms of, for example, the registration callbacks (**registerAbilityLifecycleCallback**, **unregisterAbilityLifecycleCallback**, **registerEnvironmentCallback**, and **unregisterEnvironmentCallback**) and connection and disconnection **ServiceExtensionAbility** (**connectAbility**, **connectAbilityWithAccount**, and **disconnectAbility**). For such APIs, replace their names with those of their corresponding new APIs in the lifecycle callbacks.

Most APIs are moved to the new namespace. Therefore, you can modify **import** for adaptation.

For example, the original API uses **@ohos.application.Ability**:

```js
import Ability from '@ohos.application.Ability';
```

You can directly modify **import** to switch to the new namespace:

```js
import Ability from '@ohos.app.ability.UIAbility';
```

In addition, exception handling is needed. For details, see the API reference for the new APIs.
