issue on Integrate with ionic 1

Hi, I added the Ace plugin to my Ionic 1 android project by using vs2015 plugin method and try to test Ace by following the sample of showing the battery level. However it hit the native error.

My code and error as below :-

controller :-

.controller('AccountCtrl', function($scope) {
$scope.battery = function() {
  if (ace.platform == "iOS") {
      // Objective-C code:
      // UIDevice* device = [UIDevice currentDevice];
      // [device setBatteryMonitoringEnabled:true];
      // double capacity = [device batteryLevel] * 100;
  // Invoke a static currentDevice method on UIDevice
      ace.NativeObject.invoke("UIDevice", "currentDevice", function (device) {
          // On the returned instance, call an instance method with no return value
          device.invoke("setBatteryMonitoringEnabled", true);
          // Call another instance method that returns a double
          device.invoke("batteryLevel", function (level) {
              alert("capacity = " + (level * 100) + "%");
          });
      });
  }
  else if (ace.platform == "Android") {
      // Java code:
      // BatteryManager batteryManager = getContext().getSystemService(Context.BATTERY_SERVICE);
      // int capacity = batteryManager.getIntProperty(BatteryManager.BATTERY_PROPERTY_CAPACITY);

      // Get the value of the string constant Context.BATTERY_SERVICE
      ace.NativeObject.getField("android.content.Context", "BATTERY_SERVICE", function (constant) {
          // Invoke an instance method on the Android context object to get a BatteryManager instance
          ace.android.getContext().invoke("getSystemService", constant, function (batteryManager) {
              ace.NativeObject.getField("android.os.BatteryManager", "BATTERY_PROPERTY_CAPACITY", function (constant) {
                  batteryManager.invoke("getIntProperty", constant, function (value) {
                      alert("capacity = " + value + "%");
                  });
              });
          });
      });
      }
  }
  });

Error msg :-
