How to open a new tab in Android Web View and close immediately?

Question

Java

Hello! Is there anyone who understands webview?
You just need to load the web application .... everything is OK if only internal links are opened ... but ... the VK widget is used for authorization, and when you click the authorization button, a new window opens and immediately closes window. close() in a normal browser... but in my application it doesn't close and stays on top of the original site... what should I do?

// указываем страницу загрузки
            mWebView.loadUrl("http://.../");

            // включаем поддержку JavaScript
            mWebView.getSettings().setJavaScriptEnabled(true);

            mWebView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);

            mWebView.setVisibility(View.VISIBLE);
