### 2. API Change in the **pluginComponentManager** Module
Renamed the **want** parameter **target** to more clearly indicate the intended meaning.
You need to adapt your application.
**Change Impact**
The application developed based on earlier versions must be adapted to the change. Otherwise, alarms will arise. Though the build may be successful, the API will not work as intended.
**Key API/Component Changes**
- Involved APIs:
interface PushParameterForStage {
owner: Want;
target: Want;
name: string;
data: KVObject;
extraData: KVObject;
jsonPath?: string;
}
function push(param: PushParameterForStage, callback: AsyncCallback\<void>): void;
interface RequestParameterForStage {
owner: Want;
target: Want;
name: string;
data: KVObject;
jsonPath?: string;
}
function request(param: RequestParameterForStage, callback: AsyncCallback\<RequestCallbackParameters>): void;
The **getAbilityIcon** API in [@ohos.bundle.bundleManager.d.ts](https://gitee.com/openharmony/interface_sdk-js/blob/master/api/@ohos.bundle.bundleManager.d.ts) is deleted. The **getMediaContent** API in [@ohos.resourceManager.d.ts](https://gitee.com/openharmony/interface_sdk-js/blob/master/api/@ohos.resourceManager.d.ts) can be used instead.
**Change Impact**<br>
The **getAbilityIcon** API does not take effect.
**Key API/Component Changes**<br>
The **getAbilityIcon** API is deleted from **@ohos.bundle.bundleManager.d.ts**.
**Adaptation Guide**<br>
If your application uses **getAbilityIcon** in **@ohos.bundle.bundleManager.d.ts**, replace it with **getMediaContent** in **@ohos.resourceManager.d.ts**. You need to obtain the icon ID in advance. For details, see [Usage Guide](../../../application-dev/reference/apis/js-apis-resource-manager.md#getmediacontent9).
## cl.bundlemanager.2 Bottom-Layer Capability Changed So That Only the System Resource HAP Supports Custom Permissions
Only the system resource HAP supports custom permissions. During HAP parsing, the bundle manager module parses the **definePermissions** field only in the configuration file of the resource HAP (bundle name: **ohos.global.systemres**), but not this field in other HAPs. This field is used to define permissions.
If an application requires custom permissions, add the permissions under the **definePermissions** field in the [configuration file](https://gitee.com/openharmony/utils_system_resources/blob/master/systemres/main/config.json) of the system resource HAP. For details about the permission format, see [Defining Permissions](../../../application-dev/quick-start/module-structure.md#internal-structure-of-the-definepermissions-attribute).
**Change Impact**<br>
After an upgrade to the new version image, the custom permission of the application does not take effect, and the authorization fails.
**Key API/Component Changes**<br>
The bottom-layer capability of the bundle manager module is changed. Only the system resource HAP supports custom permissions.
**Adaptation Guide**<br>
If an application requires custom permissions, add the permissions under the **definePermissions** field in the [configuration file](https://gitee.com/openharmony/utils_system_resources/blob/master/systemres/main/config.json) of the system resource HAP. For details about the permission format, see [Defining Permissions](../../../application-dev/quick-start/module-structure.md#internal-structure-of-the-definepermissions-attribute).
To sum up, except **packInfo**, which is changed to **BundlePackInfo**, the other file names are changed to start with uppercase letters.
**Change Impact**<br>
The change of the level-2 module file names does not affect the use of the level-1 module. If a level-2 module interface under **bundleManager** is directly imported to the .ts file and an error is reported during compilation on DevEco Studio, you must change the name of the imported file.
**Key API/Component Changes**<br>
The .d.ts file names in the **bundleManager** folder are changed to their respective API names in the file.
**Adaptation Guide**<br>
Generally, no adaptation is required. If a file in the **bundleManager** folder is directly imported to the application, you must change the imported file name as follows:
## cl.bundlemanager.4 LaunchType Enum Type Name Changed from STANDARD to MULTITON

The last version can be an LTS, release, beta, or monthly version, or the like. Contract compatibility, also called semantic compatibility, means that the original program behavior should remain consistent over versions.
## cl.subsystemname.x xxx Function Change (Example: DeviceType Attribute Change or Camera Permission Change. Use a short description.)
Add the number **cl.*subsystemname*.*x*** before each change title, where **cl** is the abbreviation of changelog, *subsystemname* is the standard English name of the subsystem, and *x* indicates the change sequence number (starting from 1 in ascending order).
Describe the changes in terms of functions. Example: *n* and *m* of the *a* function are changed. Developers need to adapt their applications based on the change description.
If there is a requirement or design document corresponding to the change, attach the requirement number or design document number in the description.
**Change Impact**
Describe whether released APIs (JS or native APIs) are affected or API behavior is changed.
Describe whether available applications are affected, that is, whether an adaptation is required for building the application code in the SDK environment of the new version.
**Key API/Component Changes**
List the API/component changes involved in the function change.
**Adaptation Guide**
Provide guidance for developers on how to adapt their application to the changes to be compatible with the new version.
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 based on the following information.
**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|
console.error('Failed to start ability',err.code);

## cl.ability.2 Deletion of Deprecated APIs in API Version 9
In the **Ability Exception Rectification** 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.
-**direction**, **screenDensity**, **displayId**, and **hasPointerDevice** of **Configuration** are deleted. Use **Configuration** of **@ohos.app.ability.Configuration.d.ts**.
- @ohos.application.ConfigurationConstant.d.ts

**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
importAbilityfrom'@ohos.application.Ability';
```
You can directly modify **import** to switch to the new namespace:
```js
importAbilityfrom'@ohos.app.ability.UIAbility';
```
In addition, exception handling is needed. For details, see the API reference for the new APIs.
## cl.ability.3 RestartFlag Attribute Names Changed and Unsupported Attribute Deleted in appRecovery
In the **appRecovery** API, the enum names of **RestartFlag** are changed from **NO_RESTART** upon a specific fault to **RESTART** upon a specific fault.
The **CPP_CRASH_NO_RESTART** enum is deleted.
**Change Impact**
If your application uses the **CPP_CRASH_NO_RESTART**, **JS_CRASH_NO_RESTART**, or **APP_FREEZE_NO_RESTART** attribute in versions earlier than 3.2.10.6, its behavior will change after an upgrade to 3.2.10.6.
Removed the **ohos.permission.GET_ALL_APP_ACCOUNTS** permission that is originally required for an application to call **getAllAccounts()** to obtain accessible accounts.
**Change Impact**
From this version, applications do not need the **ohos.permission.GET_ALL_APP_ACCOUNTS** permission when calling **getAllAccounts()**.
Removed the **ohos.permission.GET_ALL_APP_ACCOUNTS** permission that is originally required for an application to call **getAccountsByOwner()** to obtain the accessible accounts based on the account owner .
**Change Impact**
From this version, applications do not need the **ohos.permission.GET_ALL_APP_ACCOUNTS** permission when calling **getAccountsByOwner()**.
The following is the sample code for an application to obtain the accessible accounts based on the account owner without the **ohos.permission.GET_ALL_APP_ACCOUNTS** permission:
2. The data type declaration of the **@State**, **@Provide**, **@Link**, or **@Consume** decorated state variables can consist of only one of the primitive data types or reference data types.
The **Length**, **ResourceStr**, and **ResourceColor** types are combinations of primitive data types or reference data types. Therefore, they cannot be used by the aforementioned types of state variables.
For details about the definitions of **Length**, **ResourceStr**, and **ResourceColor**, see [Types](../../../application-dev/reference/arkui-ts/ts-types.md).
1. If the data type of a state variable decorated by a state decorator is declared as **any**, a build error will occur.
```ts
// ArkTS:ERROR Please define an explicit type, not any.
@StateisLunar:any=false
```
2. If the data type of a state variable decorated by a state decorator is declared as **Date**, a build error will occur.
```ts
// ArkTS:ERROR The @State property 'selectedDate' cannot be a 'Date' object.
@StateselectedDate:Date=newDate('2021-08-08')
```
3. If the data type of a **@State**, **@Provide**, **@Link**, and or **@Consume** decorated state variable is Length, **ResourceStr**, or **ResourceColor**, a build error will occur.
```ts
/* ArkTS:ERROR The state variable type here is 'ResourceStr', it contains both a simple type and an object type,
which are not allowed to be defined for state variable of a struct.*/
@Statemessage:ResourceStr=$r('app.string.hello')
```
**Key API/Component Changes**
N/A
**Adaptation Guide**
1. Explicitly declare the data type for state variables decorated by state decorators.
2. If a state variable decorated by a state decorator uses the **Date** object, change it to a regular variable – a variable not decorated by any decorator.
3. Adapt the **@State**, **@Provide**, **@Link**, and **@Consume** decorated variables based on the following code snippet so that they do not use the **Length(string|number|Resource)**, **ResourceStr(string|Resource)**, and **ResourceColor(string|number|Color|Resource)** types:
```ts
// Incorrect:
@Statemessage:ResourceStr=$r('app.string.hello')
// Corrected:
@StateresourceStr:Resource=$r('app.string.hello')
```
## cl.arkui.2 Initialization Rules and Restrictions of Custom Components' Member Variables
Comply with the following rules when using constructors to initialize member variables:
| **From the Variable in the Parent Component (Right) to the Variable in the Child Component (Below)**| **regular** | **@State** | **@Link** | **@Prop** | **@Provide** | **@Consume** | **@ObjectLink** |
| **@Consume** | Not supported | Not supported | Not supported | Not supported | Not supported | Not supported | Not supported |
| **@ObjectLink** | Not supported | Not supported | Not supported | Not supported | Not supported | Not supported | Not supported |
| **From the Variable in the Parent Component (Right) to the Variable in the Child Component (Below)**| **@StorageLink** | **@StorageProp** | **@LocalStorageLink** | **@LocalStorageProp** |
2. The **@ObjectLink** decorated variable cannot be directly initialized from a decorated variable in the parent component. The source of the parent component must be an array item or object attribute decorated by **@State**, **@Link**, **@Provide**, **@Consume**, or **@ObjectLink**.
```ts
letNextID:number=0;
@ObservedclassClassA{
publicid:number;
publicc:number;
constructor(c:number){
this.id=NextID++;
this.c=c;
}
}
@Component
structChild{
@ObjectLinkvarA:ClassA;
build(){
Row(){
Text('ViewA-'+this.varA.id)
}
}
}
@Component
structParent{
@LinklinkValue:ClassA
build(){
Column(){
/* ArkTS:ERROR The @Link property 'linkValue' cannot be assigned to
the @ObjectLink property 'varA'.*/
Child({varA:this.linkValue})
}
}
}
```
**Key API/Component Changes**
N/A
**Adaptation Guide**
1. When building a child component, do not perform the build on the variables decorated by **@LocalStorageLink** and **@LocalStorageProp** in the child component.
To change these variables from the parent component, use the API provided by the **LocalStorage** (such as the **set** API) to assign values to them.
2. For details about how to use **@ObjectLink**, see @ObjectLink.
## cl.LocalStorage.1 Return Type Change of the get API
Changed the return type from **get\<T>(propName: string): T** to **get\<T>(propName: string): T | undefined**.
**Change Impact**
None
## cl.arkui.LocalStorage.2 Mandatory/Optional Change of the newValue Parameter in setOrCreate
1. The second and third parameters of the **link** API are reserved for internal use by the framework. Therefore, the API is changed to contain only one parameter.
2. The return type **T** is changed to **SubscribedAbstractProperty**.
**Adaptation Guide**
```js
letstorage=newLocalStorage({"PropA":"47"});
letlinA=storage.link("PropA");
linA.set(50);
```
## cl.arkui.LocalStorage.4 setAndLink Parameter and Return Type Changes
1. The third and fourth parameters of the **setAndLink** API are reserved for internal use by the framework. Therefore, the API is changed to contain two parameters.
2. The return type **T** is changed to **SubscribedAbstractProperty**.
**Adaptation Guide**
```js
letstorage=newLocalStorage({"PropA":"47"});
letlinA=storage.setAndLink("PropA","48")
linA.set(50);
```
## cl.arkui.LocalStorage.5 prop Parameter and Return Type Changes
1. The second and third parameters of the **prop** API are reserved for internal use by the framework. Therefore, the API is changed to contain only one parameter.
2. The return type **T** is changed to **SubscribedAbstractProperty**.
**Adaptation Guide**
```js
letstorage=newLocalStorage({"PropA":"47"});
letpropA=storage.prop("PropA");
propA.set(51);// one-way sync
```
## cl.arkui.LocalStorage.6 setAndProp Parameter and Return Type Changes
1. The third and fourth parameters of the **setAndProp** API are reserved for internal use by the framework. Therefore, the API is changed to contain two parameters.
2. The return type **T** is changed to **SubscribedAbstractProperty**.
## cl.commonlibrary.1 Error Code and Information Change
The error codes and information returned by APIs of the **ArrayList**, **List**, **LinkedList**, **Stack**, **Queue**, **Deque**, **PlainArray**, **LightWeightMap**, **LightWeightSet**, **HashMap**, **HashSet**, **TreeMap**, and **TreeSet** classes are changed.
For details about the changed error codes, see [Utils Error Codes](../../../application-dev/reference/errorcodes/errorcode-utils.md).
No adaptation is required for applications developed using these APIs.
**Key API/Component Changes**
Error code information is redefined for APIs in these classes and marked using **'@throws'** in the *.d.ts file of the corresponding module.
The sample code is as follows:
**ArrayList** class before the change:
constructor();
**ArrayList** class after the change:
@throws { BusinessError } 10200012 - The ArrayList's constructor cannot be directly invoked.
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.

# Changelog of NFC JS APIs in the Communication Subsystem
## cl.nfc.1 API Change
Deprecated some NFC JS APIs in API versions 6 to 8 because the APIs cannot throw error codes, and added new APIs in API version 9 instead.
You need to adapt your application based on the following information.
**Change Impact**
The deprecated JS APIs in API versions 6 to 8 are affected. Your application needs to adapt new APIs so that it can properly implement functions in the SDK environment of the new version.
**Key API/Component Changes**
| Module | Class | Method/Attribute/Enumeration/Constant | Change Type|
In the event notification exception handling rectification, some APIs in API version 9 are marked as deprecated, and these APIs need to be deleted, according to OpenHarmony API specifications.
**Change Impacts**
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**
Deprecated APIs in API version 9 will be deleted, and they will be replaced with new ones with same names.
- The **publishAsBundle**, **cancelAsBundle**, **isNotificationSlotEnabled**, **setSyncNotificationEnabledWithoutApp**, and **getSyncNotificationEnabledWithoutApp** APIs are deleted. Replace them with APIs with same names in **api/@ohos.notificationManager.d.ts**.
- The **enableNotificationSlot** API is deleted. Replace it with **setNotificationEnableSlot** in **api/@ohos.notificationManager.d.ts**.
- The export classes **NotificationActionButton**, **NotificationBasicContent**, **NotificationContent**, **NotificationLongTextContent**, **NotificationMultiLineContent**, **NotificationPictureContent**, **NotificationFlags**, **NotificationFlagStatus**, **NotificationRequest**, **DistributedOptions**, **NotificationSlot**, **NotificationSorting**, **NotificationTemplate**, and **NotificationUserInput** are deleted. Replace them with the export classes with the same names in **api/@ohos.notificationManager.d.ts**.
- The export classes **NotificationSubscribeInfo**, **NotificationSubscriber**, **SubscribeCallbackData**, and **EnabledNotificationCallbackData** are deleted. Replace them with the export classes with the same names in **api/@ohos.notificationSubscribe.d.ts**.
**Adaptation Guide**
The original APIs are only migrated to the new namespace. Therefore, you can modify **import** to solve the adaptation problem.
If the original API uses **@ohos.commonEvent**:
```js
importcommonEventfrom'@ohos.commonEvent';
```
You can directly modify **import** to switch to the new namespace:
```js
importcommonEventfrom'@ohos.commonEventManager';
```
**@ohos.notification** is split into two namespaces. You need to select a new namespace for adaptation.
In addition, exception handling is needed. For details, see the API reference for the new APIs.
## cl.location.1 API Migration from @ohos.geolocation.d.ts to @ohos.geoLocationManager.d.ts
APIs in **@ohos.geolocation.d.ts** do not support throwing error codes. To support this function, all APIs in **@ohos.geolocation.d.ts** are migrated to the newly added **@ohos.geoLocationManager.d.ts** file, and corresponding error code description is added.
To use APIs of the location subsystem, you need to import **@ohos.geoLocationManager**.
import geoLocationManager from '@ohos.geoLocationManager';
**Change Impact**
All APIs of the location subsystem are affected. To ensure normal use of these APIs, you need to import **@ohos.geoLocationManager**.
import geoLocationManager from '@ohos.geoLocationManager';

## cl.location.1 API Migration from @ohos.geolocation.d.ts to @ohos.geoLocationManager.d.ts
APIs in **@ohos.geolocation.d.ts** do not support throwing error codes. To support this function, all APIs in **@ohos.geolocation.d.ts** are migrated to the newly added **@ohos.geoLocationManager.d.ts** file, and corresponding error code description is added.
To use APIs of the location subsystem, you need to import **@ohos.geoLocationManager**.
import geoLocationManager from '@ohos.geoLocationManager';
**Change Impact**
All APIs of the location subsystem are affected. To ensure normal use of these APIs, you need to import **@ohos.geoLocationManager**.
import geoLocationManager from '@ohos.geoLocationManager';

Rectified 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.
**Change Impacts**
If 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.
**Key API/Component Changes**
The following methods, attributes, enums, and constants are changed in API version 9 and later versions. All the APIs in the **@ohos.backgroundTaskManager.d.ts** file are migrated to the **@ohos.resourceschedule.backgroundTaskManager.d.ts** file.

**Adaptation Guide**
Import the **workScheduler** module.
```
import bundle form '@ohos.resourceschedule.workScheduler'
```
Exception handling also needs to be adapted. For details, see the [workScheduler API reference](../../../application-dev/reference/apis/js-apis-resourceschedule-workScheduler.md).
## cl.security.21 Support of No-Hash Signing Mode for HUKS
Before the change, the application passes **huks.HuksTag.HUKS_TAG_DIGEST = huks.HuksKeyDigest.HUKS_DIGEST_NONE** and HUKS uses **huks.HuksKeyDigest.HUKS_DIGEST_SHA256** for processing by default. After the change, the application passes **huks.HuksTag.HUKS_TAG_DIGEST = huks.HuksKeyDigest.HUKS_DIGEST_NONE** and HUKS does not generate a digest by default. Instead, the service performs a hash operation on the original data and then passes a hashed digest to HUKS for signing or signature verification.
**Change Impact**
Behavior of released JavaScript APIs will be changed.
The application needs to adapt these APIs so that the signing or signature verification result can be passed before and after the change.
**Key API/Component Changes**
Released JavaScript APIs remain unchanged, but parameter sets passed to the APIs are changed.
The service uses the No-Hash signing mode, and hashes the original data and then passes a hashed digest to the signing or signature verification API of HUKS. In addition, the **huks.HuksTag.HUKS_TAG_DIGEST** parameter is set to **huks.HuksKeyDigest.HUKS_DIGEST_NONE**.
value:huks.HuksKeyDigest.HUKS_DIGEST_NONE,// Set digest-none.
}
letsignOptions={
properties:signProperties,
inData:inDataAfterSha256// Set the value after hashing.
}
huks.initSession(keyAlias,signOptions);
```
For for information about the sample code, see [HUKS Development](../../../application-dev/security/huks-guidelines.md) and [HUKS](../../../application-dev/reference/apis/js-apis-huks.md).
## cl.security.22 Support for Key Calculation Parameter Specifications During Key Usage
Before the change, all parameters for key calculation must be specified when the application generates a key. After the change, only mandatory parameters need to be specified when the application generates a key, and other parameters can be passed in when the key is used. The application can specify key calculation parameters more flexibly.
**Change Impact**
Behavior of released JavaScript APIs will be changed.
The application can specify only mandatory parameters when creating a key and specify other optional parameters when using the key.
**Key API/Component Changes**
Released JavaScript APIs remain unchanged, but parameter sets passed to the APIs are changed and parameters are classified into mandatory parameters and optional parameters. For details, see [HUKS Development](../../../application-dev/security/huks-guidelines.md).
huks.generateKeyItem
huks.importKeyItem
huks.importWrappedKeyItem
huks.initSession
huks.updateSession
huks.finishSession
**Adaptation Guide**
The following uses the key generation process as an example.
```js
letkeyAlias='keyAlias';
letproperties=newArray();
// Mandatory parameter.
properties[0]={
tag:huks.HuksTag.HUKS_TAG_ALGORITHM,
value:huks.HuksKeyAlg.HUKS_ALG_RSA
};
// Mandatory parameter.
properties[1]={
tag:huks.HuksTag.HUKS_TAG_KEY_SIZE,
value:huks.HuksKeySize.HUKS_RSA_KEY_SIZE_2048
};
// Mandatory parameter.
properties[2]={
tag:huks.HuksTag.HUKS_TAG_PURPOSE,
value:
huks.HuksKeyPurpose.HUKS_KEY_PURPOSE_SIGN|
huks.HuksKeyPurpose.HUKS_KEY_PURPOSE_VERIFY
};
// Optional parameter. If this parameter is not specified when a key is generated, it must be specified when the key is used.
For for information about the sample code, see [HUKS Development](../../../application-dev/security/huks-guidelines.md) and [HUKS](../../../application-dev/reference/apis/js-apis-huks.md).
## cl.location.1 API Migration from @system.geolocation.d.ts to @ohos.geoLocationManager.d.ts
APIs in **@system.geolocation.d.ts** do not support throwing error codes. To support this function, all APIs in **@system.geolocation.d.ts** are migrated to the newly added **@ohos.geoLocationManager.d.ts** file, and corresponding error code description is added.
To use APIs of the location subsystem, you need to import **@ohos.geoLocationManager**.
import geoLocationManager from '@ohos.geoLocationManager';
**Change Impact**
All APIs of the location subsystem are affected. To ensure normal use of these APIs, you need to import **@ohos.geoLocationManager**.
import geoLocationManager from '@ohos.geoLocationManager';
**Key API/Component Changes**
| Class| API Type| Declaration| Change Type|
| -- | -- | -- | -- |
|Geolocation| class | Geolocation | Migrated to **@ohos.geoLocationManager.d.ts** and replaced by **ohos.geoLocationManager/geoLocationManager**.|
|Geolocation| interface | static getLocation(options?: GetLocationOption): void; | Migrated to **@ohos.geoLocationManager.d.ts** and replaced by **ohos.geoLocationManager/geoLocationManager.getCurrentLocation**.|
|Geolocation| interface | static subscribe(options: SubscribeLocationOption): void; | Migrated to **@ohos.geoLocationManager.d.ts** and replaced by **ohos.geoLocationManager/geoLocationManager.on#event:locationChange**.|
|Geolocation| interface | static unsubscribe(): void; | Migrated to **@ohos.geoLocationManager.d.ts** and replaced by **ohos.geoLocationManager/geoLocationManager.off#event:locationChange**.|
|| interface | GeolocationResponse| Migrated to **@ohos.geoLocationManager.d.ts** and replaced by **ohos.geoLocationManager/geoLocationManager.Location**.|
|| interface | GetLocationOption | Migrated to **@ohos.geoLocationManager.d.ts** and replaced by **ohos.geoLocationManager/geoLocationManager.CurrentLocationRequest**.|
|| interface | SubscribeLocationOption | Migrated to **@ohos.geoLocationManager.d.ts** and replaced by **ohos.geoLocationManager/geoLocationManager.LocationRequest**.|
**(Optional) Adaptation Guide**
The following sample code shows how to call **enableLocation** in the new version:
