How to browse all files in a specific directory?

Question

I\'m using Nativescript to build some app, that needs to list and present all files in the phone\'s gallery. I cannot use any \"image picker\": It just needs to present the user

Create an instance of Folder from the absolute path and use .getEntities() method to read list of files / folders within the particular folder.

import { Folder } from "tns-core-modules/file-system";

const androidPicturesPath = android.os.Environment.getExternalStoragePublicDirectory(
    android.os.Environment.DIRECTORY_PICTURES
).toString();

const folder = Folder.fromPath(androidPicturesPath);

folder.getEntities()
    .then((entities) => {
        // entities is an array of files and folders.
        entities.forEach((entity) => {
           console.log(entity.name);
        });
    }).catch((err) => {
        // Failed to obtain folder's contents.
        console.log(err);
    });

Note: Make sure your app has READ_EXTERNAL_STORAGE permission, use nativescript-permissions plugin to acquire the permission at run time.
