Edit: does not work on version 1.3.0 . Use request/response interceptors.

If you want to listen to all requests globally and display a loading widget whenever there's a request pending, you can count the requests using request/response transformers. You simply add a counter and increase on a new request and decrease it on response. I use a provider for that:

$httpProvider
  .defaults
  .transformRequest
  .push(function(data) {
      requestNotificationProvider
      .fireRequestStarted(data);
      return data;
});

And the same for transformResponse. Then the same provider holds the information on how many requests are pending and you can use them in a directive. You can read (& copy/paste the code) a full blog post on that here: http://www.kvetis.com/2014/01/angularjs-loading-widget.html There's a working demo in attached.
