Xamarin Android WebView geolocation wrong on mobile

English Exp.

The yandex map in Android WebView did not show the current location exactly.

The same page was showing correctly when opened from the browser.

It has improved after various settings have been made to WebView. The changes are as follows.

Türkçe Açk.

Android WebView içerisinde yandex harita konumu tam dogru göstermiyordu.

Ayni sayfa tarayicidan açildiginda dogru gösteriyordu.

WebView'e çesitli ayarlar yapildiktan sonra düzeldi. Degisiklikler asagidaki gibidir.

OLD CODE

myWebView.SetWebChromeClient(new WebChromeClient());
myWebView.SettingsJavaScriptEnabled = true;

NEW CODE


myWebView.SetWebViewClient(new GeoWebViewClient());
myWebView.SetWebChromeClient(new GeoWebChromeClient());

myWebView.Settings.JavaScriptCanOpenWindowsAutomatically = true;
myWebView.Settings.DomStorageEnabled = true;
myWebView.Settings.JavaScriptEnabled = true;
myWebView.Settings.SetGeolocationEnabled(true);

NEW CODE - NEW CLASSES

 
public class GeoWebChromeClient : WebChromeClient
{
	public override void OnGeolocationPermissionsShowPrompt(string origin, GeolocationPermissions.ICallback callback)
	{
		callback.Invoke(origin, true, false);
	}
}

public class GeoWebViewClient : WebViewClient
{
	public override bool ShouldOverrideUrlLoading(WebView view, IWebResourceRequest request)
	{
		Android.Net.Uri url = request.Url;
		view.LoadUrl(url.ToString());
		return true;
	}
	public override void OnReceivedSslError(WebView view, SslErrorHandler handler, Android.Net.Http.SslError er)
	{
		// Ignore SSL certificate errors
		handler.Proceed();
	}
}
