android - phonegap/jqueryを使用して、Androidデバイスのデフォルトの戻るボタンとして機能するボタンをセットアップします

Question

I'm trying to use this script to set a button on my application(html+css+js+jquery) that does the same as the default button of the android device.

This is the script:

  </script>
     <script type="text/javascript">
     $(document).ready(function(){
     $('a.back').click(function(){
         if(document.referrer.indexOf(window.location.hostname) != -1){
            parent.history.back();
            return false;
         }
      });
    });
 </script>

Then i have something like this in my code that uses the scrip:

          <a class="back">
                <img src="back.png" id="back" style="width: 75%;"></a></div>

This works well in the internet browsers but when compiling with PhoneGap does not work on android device...
