# Account Subsystem Changelog

## cl.account_os_account.1 OsAccountInfo.type Value Type Change

Changed the value type of **OsAccountInfo.type** from object to **OsAccountType** enum.

**Change Impact**

The mode for reading the **OsAccountInfo.type** value needs to be changed for the application developed based on earlier versions. Otherwise, the original service logic will be affected.

**Key API/Component Changes**

The following APIs are involved:
- AccountManager
  - queryAllCreatedOsAccounts(callback: AsyncCallback<Array<OsAccountInfo>>): void;
  - queryAllCreatedOsAccounts(): Promise<Array<OsAccountInfo>>;
  - createOsAccount(localName: string, type: OsAccountType, callback: AsyncCallback<OsAccountInfo>): void;
  - createOsAccount(localName: string, type: OsAccountType): Promise<OsAccountInfo>;
  - createOsAccountForDomain(type: OsAccountType, domainInfo: DomainAccountInfo, callback: AsyncCallback<OsAccountInfo>): void;
  - createOsAccountForDomain(type: OsAccountType, domainInfo: DomainAccountInfo): Promise<OsAccountInfo>;
  - queryCurrentOsAccount(callback: AsyncCallback<OsAccountInfo>): void;
  - queryCurrentOsAccount(): Promise<OsAccountInfo>;
  - getCurrentOsAccount(callback: AsyncCallback<OsAccountInfo>): void;
  - getCurrentOsAccount(): Promise<OsAccountInfo>;
  - queryOsAccountById(localId: number, callback: AsyncCallback<OsAccountInfo>): void;
  - queryOsAccountById(localId: number): Promise<OsAccountInfo>;

  - getOsAccountTypeFromProcess(callback: AsyncCallback<OsAccountType>): void;
  - getOsAccountTypeFromProcess(): Promise<OsAccountType>;
  - getOsAccountType(callback: AsyncCallback<OsAccountType>): void;
  - getOsAccountType(): Promise<OsAccountType>;

**Adaptation Guide**
```ts
import account_osAccount from "@ohos.account.osAccount"

let accountMgr = account_osAccount.getAccountManager();
accountMgr.createOsAccount("account_test", account_osAccount.OsAccountType.GUEST).then((accountInfo) => {
  if (accountInfo.type == account_osAccount.OsAccountType.GUEST) {
    console.log("createOsAccount successfully");
  }
  accountMgr.activateOsAccount(accountInfo.localId).then(() => {
    console.log("activateOsAccount successfully");
    accountMgr.getOsAccountTypeFromProcess().then((accountType) => {
      if (accountType == account_osAccount.OsAccountType.GUEST) {
        console.log("getOsAccountTypeFromProcess successfully");
      }
    }).catch((err) => {
      console.log("activateOsAccount err: " + JSON.stringify(err));
    });
  }).catch((err) => {
    console.log("activateOsAccount err: " + JSON.stringify(err));
  });
}).catch((err) => {
  console.log("createOsAccount err: " + JSON.stringify(err));
});
