title: webview does not download file
body: <p>Good day all,
  i have made an app but i have hit a wall.
  when you visit a website using a desktop browser like firefox or chrome and click on the download link it starts downloading the file, but when i open the same page in my android app that displays the page using webview and click on a download link nothing happens at all, it just sits there like it does not know what to do with that link. if you could help me out it would be a huge help and get me back on track again.</p>
  
  <p>this is the download link i use for a pdf file on my site:</p>
  
  <pre><code>&lt;img src="images/Art1.jpg" width="80" height="166" /&gt;&lt;a href="m2.pdf"&gt;Download&lt;/a&gt;
  </code></pre>
  
  <p>this is my main.xml file for my android app:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
      &lt;WebView  xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/webview"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent" 
      /&gt;
  </code></pre>
  
  <p>please i will be most gratefull if anyone can help point me on the right path.</p>
