I have implemented WebView in Dialog Activity and I am loading simple url into webview.

my Webview settings are as

wbView = (WebView) findViewById(R.id.wbView);
        wbView.setKeepScreenOn(true);
        wbView.getSettings().setJavaScriptEnabled(true);
        wbView.getSettings().setDomStorageEnabled(true);
        wbView.getSettings().setBuiltInZoomControls(true);
        wbView.setInitialScale(100);
        // wbView.getSettings().setUseWideViewPort(true);
        wbView.setScrollBarStyle(View.SCROLLBARS_OUTSIDE_OVERLAY);
        wbView.setWebViewClient(new MyWebViewClient());

and MyWebViewClient() contains

private class MyWebViewClient extends WebViewClient {
        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);
            prgBar.setVisibility(View.GONE);
        }

        @Override
        public void onReceivedSslError(WebView view, SslErrorHandler handler,
                SslError error) {
            Log.e("Error VAGARO", error.toString());
            prgBar.setVisibility(View.GONE);
            handler.proceed();
        }

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return false;
        }
    }

I am loading two HTML files from the Asset in the same webview its working fine but unable to load dynamic url.

I Google and find some posts on http://code.google.com/p/android/issues/detail?id=21177

My logcat shows me

Suggest me the change that I should make.

Update

I found that if I'll pass any url like "www.facebook.com" then its giving me this error, but if I'll replace it with "https://www.facebook.com" then its working fine.

The issue I found was because of the url without http:// or https://. So I appended this tag if the url doesn't contains http:// or https://.
