【React Native】安卓系统保存图片到系统相册(实例+错误解决)

  1、安装第三方库并引入

import CameraRoll from @react-native-community/cameraroll;
import RNFS from react-native-fs;

   Github参考链接:CameraRoll  RNFS

  2、添加权限

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

  3、在引用组件中引入以下代码

  否则会报"Error:Permission denied"错误,用来获取内存空间的读写权限。此处需要在顶部引入PermissionsAndroid

requestExternalStoragePermission = async () => {
        try {
            const granted = await PermissionsAndroid.request(
                PermissionsAndroid.PERMISSIONS.WRITE_EXTERNAL_STORAGE,
                {
                    title: My App Storage Permission,
                    message: My App needs access to your storage  +
                        so you can save your photos,
                },
            );
            return granted;
        } catch (err) {
            console.error(Failed to request permission , err);
            return null;
        }
    };
