在安卓版本 4.4.2 上运行时应用中断，抛出错误:[ng:areq]

当我使用离子运行时，我的应用程序路由到发现.html启动时调用DiscoverCtrl，引发错误：

Error: [ng:areq] http://errors.angularjs.org/1.4.3/ng/areq?p0=DiscoverCtrl&p1=not%20a%20function%2C%20got%20undefined

但是当我路由到 AnsweredCtrl 时，它会正确加载并且那里没有问题。此外，这仅在低于 api 级别 22 的版本中发生.当我在更高版本中运行应用程序时，它运行流畅并且没有抛出错误。我无法确定这是离子问题还是在构建应用程序时.我尝试在配置中减少 minSdk.xml但这也没有帮助。也许我犯了一个菜鸟错误。提前感谢您的帮助

发现控制器.js

 (function () {
    'use strict';
    angular
        .module('app.discover')
        .controller('DiscoverCtrl', DiscoverCtrl);
    DiscoverCtrl.$inject = ['$scope', 'ConnectivityMonitor', 'serverPath', '$stateParams', 'EndUser', '$timeout', '$compile', 'localStorageService', '$ionicHistory', 'cdnPath'];
    function DiscoverCtrl($scope,ConnectivityMonitor,serverPath,$stateParams,EndUser,$timeout,$compile,localStorageService,$ionicHistory,cdnPath) {
        var vm = this;
        ConnectivityMonitor.startWatching();
        $scope.somefunction = function(){};

    }
    })();

    'use strict';
    angular
        .module('app.answered')
        .controller('AnsweredCtrl', AnsweredCtrl);
    AnsweredCtrl.$inject = ['ConnectivityMonitor','serverPath','$scope','QuestionService','$timeout','$compile', 'localStorageService', 'cdnPath', 'QuestionListService'];
    function AnsweredCtrl (ConnectivityMonitor,serverPath, $scope, QuestionService, $timeout, $compile, localStorageService, cdnPath, QuestionListService) {
