webview: is it possible to disable auto focus mode when using the camera on a web page?

I am developing a web-based stock management application and I am using an Android phone camera to scan barcodes.
It works well, the problem is only with the autofocus of the camera. Is it possible to disable it while using the device's camera on a web page? Or is there an application that disables the camera's auto focus globally on the phone? Or some potential solution?
I hope my question is clear, thanks in advance for your help!

react native – EXPO – WebView is not processed correctly after updating to SDK 33

SDK Version: 33
Platforms (Android / iOS / web / all): Android
My application displays graphics using the fusioncharts library. Everything worked fine in SDK 32, the graphic is loaded using an html file as a base and is displayed in a web view.

Active

Webview

SDK 32 (in operation)

SDK 32

After updating to SDK 33 (Does not work, show HTML content)

SDK 33

does anyone know what happened? Was the Expo asset changed? Webview?

android: WebView or open in a browser for user guide

In an Android application I have a user guide section, which shows useful information for the user. This useful information is in the form of web pages.
So I am planning to show web content to the user. I could do this in two ways.

  • Using a web view, where web pages are displayed within the application.

    • fraud: you need to request permission from the user's Internet
  • Ask the user to open it in a browser.

    • fraud: You may have to select a browser if several browsers are installed.

Which is the favorite and why?

5.0 lollipop – Android application – error opening WebRTC URL in WebView

I am working on the development of an Android application, in which I want to open a URL in WebView. Now, if I open a simple URL in WebView (like www.google.com) it works fine. But I want to open a URL that uses WebRTC (Web Real-Time Communication) that says: "It seems that you are using an unsupported browser version." I searched google.com and discovered that WebRTC begins to be compatible with Android 5.0 (API level 21) and higher.

My version of Webview is:

using webView.getSettings (). getUserAgentString () I get the details of my web view.

reactjs: check if an inserted video ends using WebView in native reaction

I could embed a video of you tube in my application using a web view with success.
My problem is that I wanted to check if the video finished or not. In fact, I want to activate a js function when the video is going to end. Is there any way to detect that the video will end in the web view in native mode? Here is my little code:

  

If there is no way, you can tell me some alternative to do that. Thanks in advance.

android studio – Open pop-up window in my WebView

from the Windows browser when I enter a web page where after registering a new pop-up window is displayed, this pop-up window shows no problems, but when I try to do this on Android from a WebView that pop-up window does not appear, after entering The user and password is still showing the same page.

This is the code that I have in the class that extends from Fragment

                mWebView.getSettings (). setJavaScriptEnabled (true);
    mWebView.getSettings (). setAppCacheEnabled (true);
    mWebView.getSettings (). setSupportZoom (true);
    mWebView.getSettings (). setBuiltInZoomControls (true);
    mWebView.getSettings (). setDisplayZoomControls (false);
    mWebView.getSettings (). setPluginState (WebSettings.PluginState.ON);

    mWebView.getSettings (). setLoadWithOverviewMode (true);
    mWebView.getSettings (). setUseWideViewPort (true);
    mWebView.setInitialScale (1);

    mWebView.loadUrl ("https://paginaweb.es");


    mWebView.setWebChromeClient (new WebChromeClient () {
        @Override
        public boolean onCreateWindow (WebView view, boolean isDialog,
                                      boolean isUserGesture, Message resultMsg) {

            WebView newWebView = new WebView (getActivity ());

            newWebView.getSettings (). setJavaScriptEnabled (true);
            newWebView.getSettings (). setAppCacheEnabled (true);
            newWebView.getSettings (). setSupportZoom (true);
            newWebView.getSettings (). setBuiltInZoomControls (true);
            newWebView.getSettings (). setDisplayZoomControls (false);
            newWebView.getSettings (). setPluginState (WebSettings.PluginState.ON);

            newWebView.getSettings (). setLoadWithOverviewMode (true);
            newWebView.getSettings (). setUseWideViewPort (true);
            newWebView.setInitialScale (1);

            newWebView.getSettings (). setSupportMultipleWindows (true);
            view.addView (newWebView);
            WebView.WebViewTransport transport = (WebView.WebViewTransport) resultMsg.obj;
            transport.setWebView (newWebView);
            resultMsg.sendToTarget ();

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

            return true;
        }

    });

What can I do to make that pop-up window visible in the WebView?
