How to pass json data in xamarin forms web view android side - xamarin

Question

I am using xamarin forms webview and want to pass username and password json body with url like below.
I Implement Hybrid webview in xamarin forms
My PCL Code:
public class HybridWebView : WebView
{
Action<string> action;
public EventHandler<bool> WebNavigating;
public void RegisterAction (Action<string> callback)
{
action = callback;
}
public void Cleanup ()
{
action = null;
}
public void InvokeAction (string data)
{
if (action == null || string.IsNullOrEmpty(data)) {
return;
}
action.Invoke (data);
}
}
My Android HybridWebViewRenderer Code :
public class HybridWebViewRenderer : ViewRenderer<HybridWebView, Android.Webkit.WebView>
{
Context _context;
public HybridWebViewRenderer(Context context) : base(context)
{
_context = context;
}
protected override void OnElementChanged(ElementChangedEventArgs<HybridWebView> e)
{
base.OnElementChanged(e);
if (Control == null)
{
var webView = new Android.Webkit.WebView(_context);
webView.Settings.JavaScriptEnabled = true;
webView.SetWebViewClient(new MyWebViewClient(webView,e,this));
SetNativeControl(webView);
}
}
}
public class MyWebViewClient : WebViewClient
{
const string JavaScriptFunction = "function invokeCSharpAction(data){jsBridge.invokeAction(data);}";
public Android.Webkit.WebView _webView;
public Android.Webkit.WebView WebView
{
get
{
return _webView;
}
}
public ElementChangedEventArgs<HybridWebView> _element;
public MyWebViewClient(Android.Webkit.WebView view, ElementChangedEventArgs<HybridWebView> element, HybridWebViewRenderer x)
{
_webView = view;
_element = element;
if (_element.OldElement != null)
{
_webView.RemoveJavascriptInterface("jsBridge");
var hybridWebView = _element.OldElement as HybridWebView;
hybridWebView.Cleanup();
}
if (_element.NewElement != null)
{
_webView.AddJavascriptInterface(new JSBridge(x), "jsBridge");
string url = "https://Myspecific.com/Account/MobileLogin";
string postData = "{\"UserName\":\"User1\",\"Password\":\"pass123\",\"RememberMe\":false}";
_webView.PostUrl(url, Encoding.UTF8.GetBytes(postData));
}
}
output:
It shows wrong username and password
Please help...
