title: Going back to the app in Ionic framework after open the link
body: <p>I can open a link on ionic framework app in browser. But I can't go back to app after press back button. How can I do that? And also is it be able to open in facebook app automatically when click on a facebook page link?</p>
  
  <p>Here is my try:</p>
  
  <pre><code>&lt;a class="link" href="#" ng-click="openLink('http://webadres.com')"&gt;The Web Site&lt;/a&gt;
  </code></pre>
  
  <p>and the function:</p>
  
  <pre><code>$scope.openLink=function(url){
    window.open(url,'_system');
  }
  </code></pre>
