title: Facebook login button on Android Webview redirects to a blank page
body: <p>I'm trying to use a facebook login button that uses JS Facebook SDK on Android Webview. When I click it open a new page and redirects to <a href="https://www.facebook.com/dialog/oauth" rel="nofollow">https://www.facebook.com/dialog/oauth</a>... which is a blank page with a javascript code. And the webview stays here.</p>
  
  <p>I'm using:</p>
  
  <pre><code>webview.getSettings().setJavaScriptEnabled(true);
  webview.getSettings().setAppCacheEnabled(true);
  webview.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
  </code></pre>
  
  <p>Thank you!</p>
