title: Reading local XML file doesn't work on device
body: <p>Good morning,</p>
  
  <p>I have written an XML file and put it into the <code>/www/res/</code> folder of my ionic project. The app reads the file with <code>$http.get</code>.</p>
  
  <p>Within the browser, this code works fine, but on the Android device, it seems that the file can't be read. What am I doing wrong?</p>
  
  <p>Thanks in advance, Lukas</p>

  <pre><code>angular.module('topicData.service', []).factory('DataSource', ['$http',
  function($http) {
  return {
          get : function(file, callback, transform) {
              $http.get(file, {
                  transformResponse : transform
              }).success(function(data, status) {
                  console.log("Request succeeded: "+file);
                  callback(data);
              }).error(function(data, status) {
                  console.log("Request failed " + status);
                  alert(data);
              });
          }
      };
  }]);
