====== Script code ======
======= WV-create =======
<code>
// webviews work best on first page.
// After resize, reload LL

// usage: check data. and enter:
// zoom;url

LL.bindClass("android.webkit.WebView");
var context = LL.getContext();

var mydata = data.split(";");
var myZoom = mydata[0];
var myURL  = mydata[1];

var webView = new WebView(context);
    webView.getSettings().setJavaScriptEnabled(true);
    webView.setInitialScale(myZoom);

//  webView.loadUrl("http://forecast.io/embed/#lat=52.3&lon=4.68&name=Holland&units=ca" );
    webView.loadUrl("http://"+ myURL);  
return webView;
</code>

======= WV-resume =======
<code>
var refresh_interval_minutes = 60;

var myItem = LL.getEvent().getItem();
var myId   = myItem.getId();
var myView = myItem.getView();

function refreshWV() 
{ // prevent event flooding
  var nu   = new Date();
  var last = myItem.getTag(myId)||0;

  if ((nu - last) > (refresh_interval_minutes *60000))
  { //myView.reload(); <-- seams to crash when it failed to load before.
    //myView.loadUrl(myView.getUrl()); <-- alternative, if everything else fails
    myView.loadUrl( "javascript:window.location.reload( true )" );
    myItem.setTag(myId, nu);
  }  
  // store the timeout id so that it can be cleared when pausing the item
    myItem.setTag("WV", setTimeout(refreshWV, 30000));

} 

refreshWV();
</code>
======= WV-pause =======
<code>
// important: preserve the battery life and clear timeouts when the item is paused to avoid useless background activity
var id = LL.getEvent().getItem().getTag("WV");
if(id != null) {
    clearTimeout(parseInt(id));
}
</code>
