# Theme Framework Subsystem – Screenlock Management Service Changelog
## cl.screenlock.1 Permission Change of isLocked and unlock
Changed the **isLocked** and **unlock** APIs to system APIs since API version 9.
You need to adapt your application based on the following information.
**Change Impact**
The JS API needs to be adapted for applications developed based on earlier versions. Otherwise, relevant functions will be affected.
- Involved APIs:
```js
function isLocked(): boolean;
function unlock(callback: AsyncCallback<boolean>): void;
function unlock():Promise<boolean>;
```
- Before change:
```js
* Checks whether the screen is currently locked.
*
* @returns Returns {@code true} if the screen is currently locked; returns {@code false} otherwise.
* @syscap SystemCapability.MiscServices.ScreenLock
* @since 9
*/
function isLocked(): boolean;
/**
* Unlock the screen.
*
* @returns Returns {@code true} if the screen is unlocked successfully; returns {@code false} otherwise.
* @throws {BusinessError} 401 - parameter error.
* @throws {BusinessError} 202 - permission verification failed, application which is not a system application uses system API.
* @throws {BusinessError} 13200002 - the screenlock management service is abnormal.
* @syscap SystemCapability.MiscServices.ScreenLock
* @systemapi Hide this for inner system use.
* @since 9
*/
function unlock(callback: AsyncCallback<boolean>): void;
/**

*
* @returns Returns {@code true} if the screen is unlocked successfully; returns {@code false} otherwise.
* @throws {BusinessError} 401 - parameter error.

* @syscap SystemCapability.MiscServices.ScreenLock
* @systemapi Hide this for inner system use.

*/
function unlock():Promise<boolean>;
```

/**

* @syscap SystemCapability.MiscServices.ScreenLock
* @since 9
*/
function unlock():Promise<boolean>;
```
**Adaptation Guide**
Make sure the APIs are only invoked by system applications.
The code snippet is as follows:
```js
try {
let ret = screenLock.isLocked();
console.error(`Obtain whether the screen is locked successfully , ret is: ${ret}`);
} catch (error) {
console.error(`Failed to obtain whether the screen is locked, error is : ${error.code}, ${error.message}`);
}
```
```js
screenlock.unlock((err, data) => {
if (err) {
console.error(`Failed to unlock the screen, because: ${err.message}`);
return;
}
console.info(`unlock the screen successfully. result: ${data}`);
});
```
```js
screenlock.unlock().then((data) => {
console.info(`unlock the screen successfully. result: ${data}`);
}).catch((err) => {
console.error(`Failed to unlock the screen, because: ${err.message}`);
});
```
## cl.screenlock.2 Deprecation of isSecure
Deprecated the **isSecure** API since API version 9.
You need to adapt your application based on the following information.
**Change Impact**
The API can no longer be used after being deleted.
- Involved APIs:
```js
function isSecure(): boolean;
```
- Before change:
```js
function isSecure(): boolean;
```
- After change:
The API is deleted.
**Adaptation Guide**
Update the code so that the deprecated API is not used.

The code snippet is as follows:
```js
try {
let colors = wallpaper.getColorsSync(wallpaper.WallpaperType.WALLPAPER_SYSTEM);
console.log(`success to getColorsSync: ${JSON.stringify(colors)}`);
} catch (error) {
console.error(`failed to getColorsSync because: ${JSON.stringify(error)}`);
}
```
```js
let minHeight = wallpaper.getMinHeightSync();
```
```js
let minWidth = wallpaper.getMinWidthSync();
```
```js
wallpaper.restore(wallpaper.WallpaperType.WALLPAPER_SYSTEM, (error) => {
if (error) {
console.error(`failed to restore because: ${JSON.stringify(error)}`);
return;
}
console.log(`success to restore.`);
});
```
```js
wallpaper.restore(wallpaper.WallpaperType.WALLPAPER_SYSTEM).then(() => {
console.log(`success to restore.`);
}).catch((error) => {
console.error(`failed to restore because: ${JSON.stringify(error)}`);
});
```
```js
// The source type is string.
let wallpaperPath = "/data/data/ohos.acts.aafwk.plrdtest.form/files/Cup_ic.jpg";
wallpaper.setImage(wallpaperPath, wallpaper.WallpaperType.WALLPAPER_SYSTEM, (error) => {
if (error) {
console.error(`failed to setImage because: ${JSON.stringify(error)}`);
return;
}
console.log(`success to setImage.`);
});
```
```js
// The source type is string.
let wallpaperPath = "/data/data/ohos.acts.aafwk.plrdtest.form/files/Cup_ic.jpg";
wallpaper.setImage(wallpaperPath, wallpaper.WallpaperType.WALLPAPER_SYSTEM).then(() => {
console.log(`success to setImage.`);
}).catch((error) => {
console.error(`failed to setImage because: ${JSON.stringify(error)}`);
});

## cl.wallpaper.2 Deprecation of getIdSync, getFileSync, isChangeAllowed, isUserChangeAllowed, on, off, and RgbaColor
Deprecated the **getIdSync**, **getFileSync**, **isChangeAllowed**, **isUserChangeAllowed**, **on**, **off**, and **RgbaColor** APIs since API version 9.
You need to adapt your application based on the following information.
**Change Impact**
The APIs can no longer be used after being deleted.
- Involved APIs:
```js
function getIdSync(wallpaperType: WallpaperType): number;
function getFileSync(wallpaperType: WallpaperType): number;
function isChangeAllowed(): boolean;
function isUserChangeAllowed(): boolean;
function on(type: 'colorChange', callback: (colors: Array<RgbaColor>, wallpaperType: WallpaperType) => void): void;
function off(type: 'colorChange', callback?: (colors: Array<RgbaColor>, wallpaperType: WallpaperType) => void): void;
interface RgbaColor {
red: number;
green: number;
blue: number;
alpha: number;
}
```
- Before change:
```js
function getIdSync(wallpaperType: WallpaperType): number;
function getFileSync(wallpaperType: WallpaperType): number;
function isChangeAllowed(): boolean;
function isUserChangeAllowed(): boolean;
function on(type: 'colorChange', callback: (colors: Array<RgbaColor>, wallpaperType: WallpaperType) => void): void;
function off(type: 'colorChange', callback?: (colors: Array<RgbaColor>, wallpaperType: WallpaperType) => void): void;
interface RgbaColor {
red: number;
green: number;
blue: number;
alpha: number;
}
```
- After change:
The APIs are deleted.
**Adaptation Guide**
Update the code so that the deprecated APIs are not used.
