title: Sencha Touch 2 geolocation using Google Maps
body: <p>I'm trying to implement geolocation on my app written in sencha framework, but I don't really know how to implement geolocation using Sencha Touch 2 and Google Maps Api.
  I have following code:</p>
  
  <pre><code>Ext.define('App.view.WhereAmI', {
      extend: 'Ext.Container',
      xtype: 'whereAmI',
      //? fullscreen: true,
  
      requires: [
          'Ext.Map'
      ],
  
      config: {
          layout: 'fit',
          scrollable: true,
          styleHtmlContent: true,
          style: 'text-align: center; background-color:white;',
  
          items: 
          [
              {
                  xtype: 'toolbar',
                  docked: 'top',
                  title: 'Where Am I?',
                  minHeight: '60px',
                  items: [
                      {
                          ui: 'back',
                          xtype: 'button',
                          id: 'backButton',
                          text: 'Powrót',
                      },
  
                      {
                          minHeight: '60px',
                          right: '5px',
                          html: ['&lt;img src="resources/images/Image.png"/ style="height: 100%; "&gt;',].join(""),
                      },
                  ],          
              },
              {
                  xtype:'map',
              },
          ]
      },
      //launch : function () { },
  });
  </code></pre>
  
  <p>What do I exactly need to add to this view to implement marker with my current location?</p>
  
  <p>Thanks for help!</p>
