Go to the manifest folder and open the file AndroidManifest.xml.

AndroidManifest.xml.

Prescribe permissions for access to the Internet.

Go to res → layout. Open the file activity_main.xml.

If there is no code, click Split in the upper right corner.

Remove the standard code text.

Remove the standard code text.

Insert the following code in its place:

<WebView
    android:id="@+id/webView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    />

Find the MainActivity file in the java folder.

Insert the code inside the @Override method brackets:

WebView webView = findViewById(R.id.webView);

webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("https://webtraffic.guru/");

WebViewClient webViewClient = new WebViewClient() {
    @SuppressWarnings("deprecation") @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        return true;
    }

    @TargetApi(Build.VERSION_CODES.N) @Override
    public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
        view.loadUrl(request.getUrl().toString());
        return true;
    }

};
webView.setWebViewClient(webViewClient)

In the webView.loadUrl variable, insert the URL that will be opened in the application. For example,

ebView.loadUrl("https://webtraffic.guru/");
webView.loadUrl<span>(</span><a href=httpswebtraffic.guru);" class="wp-image-2075" srcset="https://webtraffic.guru/wp-content/uploads/2021/06/webview.loadurl.png 955w, https://webtraffic.guru/wp-content/uploads/2021/06/webview.loadurl-300x226.png 300w, https://webtraffic.guru/wp-content/uploads/2021/06/webview.loadurl-768x579.png 768w" sizes="(max-width: 955px) 100vw, 955px" />
