title: android webview zoom in/out bug
body: <p>I had set zoom control on webview</p>
  
  <pre><code>webview.getSettings().setBuiltInZoomControls(true);
  webview.getSettings().setSupportZoom(true);
  </code></pre>
  
  <p>But it work not correctly.</p>
  
  <p>If i touch screen for zoom out (multi touch use finger) it working in a state of touching screen.</p>
  
  <p>But if i detach screen, it comeback initial size.</p>
  
  <p>and zoom control remember zoom out operation working correctly.so i do again again again </p>
  
  <p>And zoom control '+' button change disable state ( MAX zoom out state )</p>
  
  <p>But webpage is still not change . (zoom was not work)</p>

  <p>The webpage is html made by programally </p>
  
  <p>like this</p>
  
  <pre><code>&lt;meta http-equiv=’Content-Type’ content=’text/html; charset=utf-8′ /&gt;
  &lt;html&gt;
  &lt;body&gt;
  &lt;img src="my image url" width="100%"&gt;&lt;/img&gt;&lt;/br&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>It's so simple html source.</p>
