title: Disable file acess within webview without disabling file upload
body: <p>I want to disable file URL access within webview such that webview should not able to load files like-</p>
  
  <pre><code>    webView.loadUrl("file:///android_asset/html/index.html");
  </code></pre>
  
  <p>For that I can use <code>setAllowFileAccess(false);</code>
  But I don’t want to disable file upload feature inside webview done using openFileChooser,onShowFileChooser.</p>
  
  <p>Will putting <code>setAllowFileAccess(false)</code> affects file upload feature inside webview also?</p>
