title: Android, extract javascript variable from webview using javascript interface
body: <p>How can I extract this variable bellow from a website to my android code?
  I guess it should work using javascript interface but how do I get it?</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
      var Ids = "[4161, 104, 121, 202, 1462]";
  &lt;/script&gt;
  </code></pre>
  
  <p>And I can't change the code on the website to a method that returns the value.</p>
  
  <p>Any suggestions?</p>
