Send data from mobile web browser to android app webview

I have a simple Xamarin android app with a webview to display my own website.

I need to validate the email provided in the registration form, so I send a email with an "Activation link". When the user verify the address, is redirected to a confirmation page opened in the mobile default browser and automatically logged in. I need to send some data to notify the webview in the app about the new user status to login in the app too.

If the complete flow is done in a web browser (mobile or PC), it works fine.

Both solutions works fine sharing data from tab to tab in a browser (Chrome), but no access from browser to webview.

This is my webview definition:

        WebView webView = FindViewById<WebView>(Resource.Id.webView);
        webView.SetWebViewClient(new CustomizeWebviewClient(this));
        webView.SetWebChromeClient(new ExtendedChromeClient(this));

        webView.LoadUrl("http://myweb.com");
        webView.Settings.JavaScriptEnabled = true;
        webView.Settings.SetSupportZoom(true);
        webView.Settings.BuiltInZoomControls = true;
        webView.Settings.DisplayZoomControls = false;
        webView.Settings.LoadWithOverviewMode = true;
        webView.Settings.UseWideViewPort = true;
        webView.Settings.SetSupportMultipleWindows(true);
        webView.Settings.DomStorageEnabled = true;
        webView.Settings.DatabaseEnabled = true;
        if (Build.VERSION.SdkInt < BuildVersionCodes.Kitkat)
        {
            string dbPath = Application.Context.GetDir("database", FileCreationMode.Private).Path;
            webView.Settings.DatabasePath = dbPath;
        }

        webView.ScrollBarStyle = ScrollbarStyles.OutsideOverlay;
        webView.ScrollbarFadingEnabled = true;

After lost several days searching and trying a lot of solutions that worked for others ( Intent filters, Deep links, App Links, ...), finally, I have decide to change the way to solve my problem: Instead to send a verification link, I'll send a verification code that the user has to insert in my web/app.

This way I can forget past, present and future problemas with:

  • Different Android versions

  • Works in all the emails providers and never will depend on the security policy changes of them

  • Totally cross browser and versions of them

  • Totally cross platform and device

  • The user is responsible to manage the flow between tabs or browser and app
