title: how to show progress bar on webview?
body: <p>I am trying to open a webpage in my application using <code>WebView</code>. When I open webpage it shows me blank screen for a while and then open that page in browser inside my application.</p>
  
  <p>Anyone suggest me how to show progress or get rid of that blank screen which comes during loading of webview?</p>
  
  <p>I am using following code:</p>
  
  <pre><code>WebView mWebView = (WebView) findViewById(R.id.mywebview);
  mWebView.getSettings().setJavaScriptEnabled(true);
  
  // error handling
  final Activity activity = this;
  
  mWebView.setWebViewClient(new WebViewClient() {
      public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
          Toast.makeText(activity, "Oh no! " + description, Toast.LENGTH_SHORT).show();
      }
  });
  
  // error  handling
  
  mWebView.loadUrl(URL);
  mWebView.setWebViewClient(new HelloWebViewClient());
  </code></pre>
