I am trying to create a mobile app via Xamarin for Android which has a WebView that shows a website, problem is that normal buttons fire, but javascript events do not fire. I have enabled Javascript, but no luck.

How to enable javascript in your android webview include the following code in MainActivity.OnCreate:
localWebView.Settings.JavaScriptEnabled = true;
localWebView.Settings.DomStorageEnabled = true;
The first allows javascript to work, the second will allow values to be stored in your HTML/DOM.

It is probably due to insecure content stuff that is introduced in lollipop.
if (Build.VERSION.SdkInt >= BuildVersionCodes.Lollipop)
webView.Settings.MixedContentMode = MixedContentHandling.AlwaysAllow;
Try adding these lines and see if that works.

After this webview started performing at intended
