here is my custom service implementation
(function () {
    var myModule = angular.module('app', ['onsen']);
    myModule.service('service', ["$http", function ($http) {
        var test = function (usertoken) {
            alert("fffffffffffffffffffff");

        }
        return {
            getUserSites: getUserSites
        };
    }]);
})();

and here is my module implementation :
(function () {
    var myApp = angular.module('app', ['onsen']);

    var MainController = function ($scope, $http, $interval, service) {
        $scope.clciclme = function () {
            alert("HIIIIIIIIIIIIIIIIIIII");
        }
    }
    myApp.controller('MainController', MainController);
})();

Please help, what is making this error ?

A:

You are using the module setter syntax twice, that is:
var myApp = angular.module('app', ['onsen']);

You are creating the app module twice.  To use the getter syntax, simply don't pass the second parameter (the array):
var myApp = angular.module('app');

Your code would look like this:
Controller:
(function () {
    var myApp = angular.module('app', ['onsen']); // use the setter syntax one time

    var MainController = function ($scope, $http, $interval, service) {
        $scope.clciclme = function () {
            alert("HIIIIIIIIIIIIIIIIIIII");
        }
    }
    myApp.controller('MainController', MainController);
})();

Service:
(function () {
    var myModule = angular.module('app'); // use the getter syntax all subsequent times

    myModule.service('service', ["$http", function ($http) {
        var test = function (usertoken) {
            alert("fffffffffffffffffffff");

        }
        return {
            getUserSites: getUserSites
        };
    }]);
})();
