cl.wallpaper.1 getColorsSync、getMinHeightSync、getMinWidthSync、restore、setImage接口使用权限变更
从API9开始，变更为systemapi，停止对三方应用开放。
开发者需要根据以下说明对应用进行适配。
变更影响
基于此前版本开发的应用，需适配变更的js接口，变更前的接口已经不能正常使用了，否则会影响原有功能。

适配指导
该接口变更为系统应用后，三方应用已无法使用。 系统应用可正常使用。 示例代码如下：
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)}`);
}
let minHeight = wallpaper.getMinHeightSync();
let minWidth = wallpaper.getMinWidthSync();
wallpaper.restore(wallpaper.WallpaperType.WALLPAPER_SYSTEM, (error) => {
if (error) {
console.error(`failed to restore because: ${JSON.stringify(error)}`);
return;
}
console.log(`success to restore.`);
});
wallpaper.restore(wallpaper.WallpaperType.WALLPAPER_SYSTEM).then(() => {
console.log(`success to restore.`);
}).catch((error) => {
console.error(`failed to restore because: ${JSON.stringify(error)}`);
});
// source类型为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.`);
});
// source类型为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 getIdSync、getFileSync、isChangeAllowed、isUserChangeAllowed、on、off、RgbaColor接口废弃变更
从API9开始，废弃此接口。
开发者需要根据以下说明对应用进行适配。
变更影响
该接口删除无法再使用，请使用进行更新使用，否则会影响原有功能。
- 涉及接口
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;
}
- 变更前：
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;

interface RgbaColor {
red: number;
green: number;
blue: number;
alpha: number;
}
- 变更后：删除接口，停止对外开放。
