  <p>How to make to webview returns to the previous page and does not show about: blank?
  here is my code:</p>
  <pre><code>@Override
      public void onBackPressed() {
          if (mWebView.canGoBack()) {
              mWebView.goBack();
              return;
          }
          else {
              finish();
          }
  
          super.onBackPressed();
      }
   @Override
          public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
              mbErrorOccured = true;
              showErrorLayout();
              super.onReceivedError(view, errorCode, description, failingUrl);
              loadErrorPage();
          }
      }
  
      private void showErrorLayout() {
          mlLayoutRequestError.setVisibility(View.VISIBLE);
      }
  
      private void loadErrorPage() {
          if(mWebView!=null){
              String htmlData =&quot;&lt;html&gt;&lt;body&gt;&lt;div align= center &gt;Check your internet!&lt;/div&gt;&lt;/body&gt;&quot; ;
              mWebView.loadUrl(&quot;about:blank&quot;);
              mWebView.loadDataWithBaseURL(null,htmlData, &quot;text&quot;, &quot;utf-8&quot;,null);
              mWebView.invalidate();
          }
      }
  </code></pre>
  <p>For example, the Google page loaded, then an error occurred and about: blank was loaded, and when the page is reloaded, the WebView reloads about: blank and not the Google page. How to make the Google page load on reload?</p>
