Question

Answer 1

Hi @Bank ,
If you are using WebView, you can customize the Handler and override the CreatePlatformView method to set your WebViewClient and WebChomeClient:

config handler in MauiProgram

 builder.UseMauiApp<App>().ConfigureMauiHandlers(Handlers =>  
            {  
    #if __ANDROID__  
               Handlers.AddHandler(typeof(MyCustomWebView), typeof(MyCustomWebViewHandler));  
    #endif  
            });  

Set SetWebViewClient in MyCustomWebViewHandler

 partial class MyCustomWebViewHandler: WebViewHandler  
    {  
        protected override Android.Webkit.WebView CreatePlatformView()  
        {  
            Android.Webkit.WebView customWebView =  new Android.Webkit.WebView(Android.App.Application.Context);  
            customWebView.SetWebViewClient(new MyCustomWebClient());//your WebViewClient   
           customWebView.SetWebChromeClient(new MyCustomWebChomeClient());// your WebChomeClient  
            return customWebView;  
        }  
    }  

For more details , refer to Customize .NET MAUI controls with handlers
