Unknown provider: $ stateProviderProvider <- $ stateProvider

.controller('myCtrl', function($scope,$localstorage,$stateProvider, $urlRouterProvider) {

  $scope.getNews= function(){
  $stateProvider.stat('app.news')
}

});

Why am I getting an unknown provider error? I have already entered dependecy in my controller.

You do what you try to add $ stateProvider to the controller, and not to your app.config () function. If you look at the UI-Router docs, you will see that you have to configure it in app.config, which will load before your controller starts.

You can read data from the $ state provider in your controller, but only when you use it as a service. This may be a confusing difference. I will try to explain below.
