If I understood you correctly, you want to have the option to select how to open the web link - inside your app, or within another app's (browser) context.
If this is correct, then you can use Xamarin.Essentials: Browser functionality.
public async Task OpenBrowser(Uri uri)
{
await Browser.OpenAsync(uri, BrowserLaunchMode.SystemPreferred);
}
Here the important property is the BrowserLaunchMode flag, which you can learn more about here
Basically, you have 2 options - External & SystemPreferred.
- The first one is clear, I think - it will open the link in an external browser.
- The second options takes advantage of Android's Chrome Custom Tabs & for iOS - SFSafariViewController
P.S. You can also customise the PreferredToolbarColor, TitleMode, etc.
Edit: Based from your feedback in the comments, you want to control how to open href links from your website.
If I understood correctly, you want the first time that you open your site, to not have the nav bar at the top, and after that to have it. Unfortunately, this is not possible.
You can have the opposite behaviour achieved - the first time that you open a website, to have the nav bar and if the user clicks on any link, to open it externally (inside a browser). You have 2 options for this:
- To do it from your website - change the
a tag's target to be _blank like this;
- To do it from your mobile app - create a Custom renderer for the WebView. In the Android project's renderer implementation, change the
Control's WebViewClient like so:
public class CustomWebViewClient : WebViewClient
{
public override bool ShouldOverrideUrlLoading(Android.Webkit.WebView view, IWebResourceRequest request)
{
Intent intent = new Intent(Intent.ActionView, request.Url);
CrossCurrentActivity.Current.StartActivity(intent);
return true;
}
}
