Loading https via android webview

I'm new to android and in my app, I need to get connection to an https for payment action and here's how my webview currently looks like when I try to make connection.

I've looked up on the web for solutions to loading https via overriding onReceivedSslError method to ignore the error and proceed onwards. So, I have done so as the following.

Here's my webview getting its settings:

web = (WebView)findViewById(R.id.web); // setting WebViewClient web.setWebViewClient(new WebViewClientClass()); web.getSettings().setDomStorageEnabled(true); web.getSettings().setJavaScriptEnabled(true); web.loadUrl(orderSheetUrl); 

where orderSheetUrl is the https url to which my payment action takes the user to.

Below is my WebViewClient class:

private class WebViewClientClass extends WebViewClient { @Override public void onPageStarted(WebView view, String url, Bitmap favicon) { Log.d("WebView", "onPageStarted " + url); } @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { Log.d("WebView", "in shouldOverrideUrlLoading"); view.loadUrl(url); return true; } @Override public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) { Log.d("WebView", "onReceivedSslError"); handler.proceed(); // Ignore SSL certificate errors } @Override public void onPageFinished(WebView view, String url) { Log.d("WebView", "onPageFinished " + url); } } 

The problem here is then I try to load the link, but find in my log that only the logs for onPageStarted and onPageFinished is being called.

Here's my logs:

12-13 17:06:31.760 8694-8694/? D/WebView: onPageStarted :"https://alpha-bill.payco.com/easyLogin/201512132004116802?inAppYn=Y" 12-13 17:06:31.760 8694-8694/?

I really don't get why the onReceivedSslError method is not called even when I access a url starting with https, which from my understanding should require a certificate to have an access.

Have I done something wrong with implementing my WebViewClient? Or is there any other way around this? Thanks in advance for the help.

P.S. my target API is 23 and minimum is 15.
