I currently have an app that displays a webview, and I wish to display the contents of a gdrive folder in this webview, and allow all users of the app to view files in that folder.
With the code that I currently have, I can't display the folder, and I copied the share link, with the permission that anyone with the link can view.

What I have tried:

import androidx.appcompat.widget.Toolbar;

import android.app.DownloadManager;
import android.graphics.Bitmap;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.webkit.DownloadListener;
import android.webkit.WebResourceRequest;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;

public class info extends base {
private WebView web;
private Toolbar mtoolbar;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_info);
        mtoolbar=(androidx.appcompat.widget.Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(mtoolbar);
        web=findViewById(R.id.web);
        web.setWebViewClient(new client());
        WebSettings ws=web.getSettings();
        ws.setJavaScriptEnabled(true);
        web.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
        web.clearCache(true);
        web.clearHistory();
        web.setDownloadListener(new DownloadListener() {
            @Override
            public void onDownloadStart(String url, String userAgent, String contentDisposition, String mimetype, long contentLength) {
                DownloadManager.Request req=new DownloadManager.Request(Uri.parse(url));
                req.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
                DownloadManager dm=(DownloadManager)getSystemService(DOWNLOAD_SERVICE);
                dm.enqueue(req);
                Toast.makeText(getApplicationContext(),"La descarga ha iniciado....",Toast.LENGTH_SHORT).show();
            }
        });
        web.loadUrl("url");
    }

    private class client extends WebViewClient {
        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);
        }

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);
        }
    }
}
