How to clear webview cache in .net maui Android?

Question

I am authenticating through WebView .Net Maui Android, and acquire a token on successful login, I have experienced that on re-login scenarios the authentication details is not requested again, because the browser is storing the previously logged in user. I have to clear the browser’s cookies section to get rid of the useless previous user’s details.

 <WebView x:Name="Browser"         
   WidthRequest="300"        
   HeightRequest="1000"       
    Navigating="Browser_Navigating"     
      Navigated="webOnEndNavigating" />

 public UAEPass()
 	{ 		
InitializeComponent();        
  Browser.Source = "URL"; 
  
    }

Hello,

I have to clear the browser’s cookies section to get rid of the useless previous user’s details.

You can do it by following code, you need to clear the cache and delete the all the Application Cache and the HTML5 Web Storage.

//Clear all the Application Cache, Web SQL Database and the HTML5 Web Storage
Android.Webkit.WebStorage.Instance.DeleteAllData();


// Clear all the cookies
Android.Webkit.CookieManager.Instance.RemoveAllCookies(null);
Android.Webkit.CookieManager.Instance.Flush();

If you want to do clear cache at the runtime, you can copy above code to the onCreate method of MainActivity.cs, then you can send messenger to invoke the clear cache code.
