title: Sencha Touch 2 app doesn't show google map on Samsung Galaxy Ace
body: <p>I've written an app which shows current location on map.
  The problem is that it works on Galaxy Tab 10.1, HTC Desire, Desire Z, Galaxy S
  BUT when I use Samsung Galaxy Ace or emulator with Android 2.3.3 it doesn't work - t shows me just grey screen.</p>
  
  <p>Code:</p>
  
  <pre><code>Ext.define('MyApp.view.WhereAmI', {
  extend: 'Ext.Container',
  xtype: 'whereAmI',
  
  config: {
      layout: 'fit',
      scrollable: true,
      styleHtmlContent: true,
      style: 'text-align: center; background-color:white;',
  
      items: 
      [
          {
              xtype: 'toolbar',
              docked: 'top',
              title: 'Where am I?',
              items: [
                  {
                      ui: 'back',
                      xtype: 'button',
                      id: 'back',
                      text: 'Back'
                  }
              ]       
          },
          {
              xtype: 'mapview'
          }
      ]
  }
  });
  </code></pre>
  
  <p>mapview:</p>
  
  <pre><code>Ext.define("MyApp.view.MapView", {
      extend: "Ext.Map",
      xtype: 'mapview',
      config: {
          useCurrentLocation: true,
          mapOptions:{
              zoom: 14,
          },
          listeners: {
              maprender : function(comp, map){
                  new google.maps.Marker({
                      position: new google.maps.LatLng(this._geo.getLatitude(), this._geo.getLongitude()),
                      map: map
                  });                 
              },
          }
      },
  })
  </code></pre>
  
  <p>and of course in index.html:</p>
  
  <pre><code>&lt;script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>Is it possible to make it works?</p>
