    getPicture : function() {
      var deferred = $q.defer();

      var onError = function(err) {
        deferred.reject(err);
      };

      // my options here

      $ionicPlatform.ready(function() {
        $cordovaCamera.getPicture(options).then(onSuccess, onError);
      });

      return deferred.promise;
    }
  }; …
