title: Activity indicator in Titanium not working
body: <p>I want to show an activity indicator in my screen using Titanium but it is not showing me any result. It is not showing any progress sign.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>var actInd = Titanium.UI.createActivityIndicator();
  
  actInd.message = 'Please wait...';
  //message will only shows in android.
  
  var self = Ti.UI.createWindow({
      title : "About",
      navBarHidden : false,
      barColor : "#50b849",
      backgroundColor : "#2d2d2d",
  });
  self.add(actInd);
  actInd.show();
  self.orientationModes = [Titanium.UI.PORTRAIT];
  
  var text = Ti.Filesystem.getFile(Ti.Filesystem.resourcesDirectory + "info.txt").read();
  
  var infoText = Ti.UI.createTextArea({
      width : "100%",
      height : "100%",
      color : "#fff",
      backgroundColor : "#2d2d2d",
      value : text,
      editable : false,
      scrollable : false,
      font : {
          fontWeight : 'bold',
          fontSize : 20,
          fontFamily : 'Helvetica Neue'
      },
      textAlign : Ti.UI.TEXT_ALIGNMENT_CENTER,
      autoLink : Ti.UI.AUTODETECT_LINK
  });
  
  infoText.addEventListener("click", function() {
      Ti.Platform.openURL("http://tellusanotherone.org/c2p");
  });
  
  var scrollView = Ti.UI.createScrollView({
      width : "100%",
      height : "100%",
      verticalBounce : true,
      scrollType : "vertical",
  });
  scrollView.add(infoText);
  self.add(infoText);
  
  return self;
  </code></pre>
  
  <p>Thanks in advance.</p>
