title: Android webview href not support in html page
body: <p>I want to load to a about.html page inside asset folder by clicking a button in index.html inside android webview.</p>
  
  <p>Here's the code:</p>
  
  <p>Button:</p>
  
  <pre><code>&lt;a href="about.html"&gt;About&lt;/a&gt;
  </code></pre>
  
  <p>Java:</p>
  
  <pre><code>    WebView browser = (WebView) findViewById(webview);
      browser.getSettings().setJavaScriptEnabled(true);
      browser.setWebChromeClient(new WebChromeClient());
      browser.loadUrl("file:///android_asset/www/index.html");
      browser.setWebViewClient(new WebViewClient() {
          @Override
          public boolean shouldOverrideUrlLoading(WebView view, String url) {
              view.loadUrl(url);
              return false;
          }
      });
  </code></pre>
  
  <p>But the problem is when i click on button it doesn't load about.html but if I add a javascript function with below code it works.. but i want to use href.</p>
  
  <p>Code:</p>
  
  <pre><code>&lt;button onclick="about()"&gt;About&lt;/button&gt;
   &lt;script&gt;
          function about() {
              location.href = "about.html";
          }   
  &lt;/script&gt;
  </code></pre>
  
  <p>How do I solve it?</p>
