How to run http call as background in ionic Framework?

I am using ionic Framework. i have multiple HTTP service which is working fine. Now problem is that whenever i get response of any http call. i can't proceed further.

Can we run HTTP Service as a background process. So my application continues works without waiting for result.

here is my code 

articleService.getArticles().then(function() {

    },function(err){

    });

and sercvice code 

$http({
                url: "http://myservice.com",
                data: { user_id: 1 },
                method: 'POST',
                withCredentials: true,
            }).success(function (data) {
                deferred.resolve(data);
            }).error(function (err) {
             deferred.resolve(0);
            })
            return deferred.promise;
        }

Any idea? I need a solution in ionic framework which will work both for ios and andriod?

Thanks

try to use html5 web workers what u need to do is multithreading and because that javascript is single threading environment you have to web workers

Look at this plunker this what you need and it is all angularjs so will work with ionic.

var app = angular.module('angularjs-starter', []);

app.config(function($routeProvider) {
    $routeProvider.
      when('/', {controller:'StartCtrl', templateUrl:'start.html'}).
      when('/main', {controller:'MainCtrl', templateUrl:'main.html'}).
      otherwise({redirectTo:'/'});
});

app.controller('MainCtrl', function($scope, Poller) {
  $scope.name = 'World';
  $scope.data = Poller.data;
});
app.controller('StartCtrl',function(){});
app.run(function(Poller) {});

app.factory('Poller', function($http, $timeout) {
  var data = { response: {}, calls: 0 };
  var poller = function() {
    $http.get('data.json').then(function(r) {
      data.response = r.data;
      data.calls++;
      $timeout(poller, 1000);
    });

  };
  poller();

  return {
    data: data
  };
});

Maybe i misunderstand your question but i think your service code is wrong.

Try something like this

myApp.factory('articleService', function($http) {
    return {
        getArticles: function getArticles() {
              return $http({...}); // $http returns a promise, so you dont need your own defer.promise
        }
    }
});


//usage
//first: send or get data async
articleService.getArticles().then(function(resp){
    alert('called second');
    ...
});
// second: do something else, this will not wait for your response
alert('called first');
