Adaptation Guide

For example, refer to the code snippet below to call an API to select an image:

import picker from '@ohos.file.picker';

async function example() {
    try {  
        let PhotoSelectOptions = new picker.PhotoSelectOptions();
        PhotoSelectOptions.MIMEType = picker.PhotoViewMIMETypes.IMAGE_TYPE;
        PhotoSelectOptions.maxSelectNumber = 1;
        let photoPicker = new picker.PhotoViewPicker();
        photoPicker.select(PhotoSelectOptions).then((PhotoSelectResult) => {
            if (PhotoSelectResult !== undefined) {
                console.info("PhotoViewPicker.select pass, PhotoSelectResult uri: " + JSON.stringify(PhotoSelectResult));
            } else {
                console.error("PhotoViewPicker.select PhotoSelectResult is undefined");
            }
        }).catch((err) => {
            console.error("PhotoViewPicker.select fail, err: " + err);
        });
    } catch (err) {
        console.error("PhotoViewPicker fail, err: " + err);
    }
