title: Titanium context issue on Android Emulator
body: <p>Am running an app that is working fine in my iOS simulator, but it crashes con my Android emulator, cuz it says that I have not defined a variant.</p>
  
  <p>Here is my example code:</p>
  
  <pre><code>/*app.js*/
  var myApp = {};
  myApp.ui = require("ui");
  myApp.ui.createAppTabGroup.open();
  
  /*ui.js*/
  function createAppTabGroup() {
      var tabGroup = Titanium.UI.createTabGroup();
      myApp.fugitivesTab = Titanium.UI.createTab({
      title: L('fugitives'),
          window: fugitives
      });
  };
  </code></pre>
  
  <p>I'm declaring "var myApp" before I make the require("ui"), so it should works without problems, and in fact, it works on iOS simulator, but in Android says "myApp is not defined in line <code>xx myApp.fugitivesTab = Titanium.UI.createTab({"</code></p>
  
  <p>Any suggestion?</p>
