title: HTML file input in android webview (android 4.4, kitkat)
body: <p>I was using the <code>&lt;input type="file"&gt;</code> on the android webview.
  I got it working thanks to this thread: 
  <a href="https://stackoverflow.com/questions/5907369/file-upload-in-webview">File Upload in WebView</a></p>
  
  <p>But the accepted answer (or any other) no longer works with android 4.4 kitkat webview.</p>
  
  <p>Anybody knows how to fix it? </p>
  
  <p>It doesn't work with target 18 either.</p>
  
  <p>I've looking some android 4.4 source code and it seems that the WebChromeClient hasn't changed, but I think the <code>setWebChromeClient</code> no longer works on the kitkat webview, or at least not the <code>openFileChooser</code> function.</p>
