Android WebView not loading an HTTPS URL

public void onCreate(Bundle savedInstance)
{       
    super.onCreate(savedInstance);
    setContentView(R.layout.show_voucher);
    webView=(WebView)findViewById(R.id.webview);
    webView.getSettings().setJavaScriptEnabled(true);
    webView.getSettings().setBuiltInZoomControls(true);
    String url ="https://www.paymeon.com/Vouchers/?v=%C80%8D%B1x%D9%CFqh%FA%84%C35%0A%1F%CE&iv=%25%EE%BEi%F4%DAT%E1"
    //webView.loadUrl(url); // Not Working... Showing blank
    webView.loadUrl("http://www.yahoo.com"); // its working    
}

When I try to load a URL in the WebBView it only shows a blank screen. If I load Google.com or yahoo.com it's working fine.

Solution 1:

Please visit this link:

Add this overriding method to your WebViewClient implementation. You'll need to compile it with Android SDK 2.2 (API level 8) or later. The method appears in the public SDK as of 2.2 (API level 8) but we've tested it on devices running 2.1, 1.6 and 1.5 and it works on those devices too (so obviously the behaviour has been there all along).

 @Override
public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
    handler.proceed(); // Ignore SSL certificate errors
}

this will help you.

Solution 2:

Per correct answer by fargth, follows is a small code sample that might help.

First, create a class that extends WebViewClient and which is set to ignore SSL errors:

// SSL Error Tolerant Web View Client
private class SSLTolerentWebViewClient extends WebViewClient {

            @Override
            public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
                handler.proceed(); // Ignore SSL certificate errors
            }

}

Then with your web view object (initiated in the OnCreate() method), set its web view client to be an instance of the override class:

 mWebView.setWebViewClient(
                new SSLTolerentWebViewClient()
        );

Solution 3:

To properly handle SSL certificate validation and avoid application rejection from Google according new Security Policy, Change your code to invoke SslErrorHandler.proceed() whenever the certificate presented by the server meets your expectations, and invoke SslErrorHandler.cancel() otherwise.

For example, I add an alert dialog to make user have confirmed and seems Google no longer shows warning.

    @Override
    public void onReceivedSslError(WebView view, final SslErrorHandler handler, SslError error) {
    final AlertDialog.Builder builder = new AlertDialog.Builder(this);
    String message = "SSL Certificate error.";
        switch (error.getPrimaryError()) {
            case SslError.SSL_UNTRUSTED:
                message = "The certificate authority is not trusted.";
                break;
            case SslError.SSL_EXPIRED:
                message = "The certificate has expired.";
                break;
            case SslError.SSL_IDMISMATCH:
                message = "The certificate Hostname mismatch.";
                break;
            case SslError.SSL_NOTYETVALID:
                message = "The certificate is not yet valid.";
                break;
        }
        message += " Do you want to continue anyway?";

        builder.setTitle("SSL Certificate Error");
        builder.setMessage(message);
    builder.setPositiveButton("continue", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            handler.proceed();
        }
    });
    builder.setNegativeButton("cancel", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            handler.cancel();
        }
    });
    final AlertDialog dialog = builder.create();
    dialog.show();
}

After this changes it will not show warning.

Solution 4:

Remove the below code it will work

 super.onReceivedSslError(view, handler, error);
