title: Android WebViewClient onReceivedError is not called for a 404 error
body: <p>hi
  <br>
  In a list view i have an webview which should load a image file from the server,when there is no image present i need a dummy image .I tried </p>
  
  <pre><code>holder.image.setWebViewClient(new WebViewClient()
  {
                    @Override
                  public void onReceivedError( WebView view, int errorCode, String description, String failingUrl) 
                  {
  
                      System.out.println("description error" + description);
                      view.setVisibility( View.GONE );
  
                  }
  
                  @Override
                  public void onPageFinished(WebView view, String url) {
  
                      view.setVisibility( View.VISIBLE );
  
  
                  }
  
  
     }); 
  </code></pre>
  
  <p>I have this webview with an dummy image in a FrameLayout, onPageFinished listener is called  after every image url is loaded, but onReceivedError is not called for a url which produce a 404 error.Any guess how to do it.</p>
