title: EventListener "online" "offline" doesn't work in Android Cordova WebView
body: <p>I have a little problem with Android Cordova Webview. My app doesn't trigger the eventListener "online/offline".</p>
  
  <p>I try many types of listeners:</p>
  
  <pre><code>window.addEventListener('online', function() {alert('ON LISTENER');});
  document.addEventListener('online', function() {alert('ON LISTENER');});
  $(window).on("online", function() {alert('ON LISTENER');});
  </code></pre>
  
  <p>but none work in android webview</p>
