How to find device os and version in ionic

Issue

I have worked on few tutorials and at last found something regarding this in ionic framework.....

They gave some codes that use ionic native and i did the same by embedding the below code:

//Display OS name and version (Start)
import { Device } from 'ionic-native';


console.log('Device OS is: ' + Device.device.platform);
console.log('Device OS Version is: ' + Device.device.version);

//Display OS name and version (End) 

While using ionic serve i got this in the console:

'Device OS is: undefined'
'Device OS version is: undefined'

Then i guessed it wont work in browser and i tried building and run in my phone but still the same log comes...

PS: I have just started with ionic

Thank you in advance :)

Solution

Please see this link http://ionicframework.com/docs/api/utility/ionic.Platform/

angular.module('PlatformApp', ['ionic'])
.controller('PlatformCtrl', function($scope) {

  ionic.Platform.ready(function(){
    // will execute when device is ready, or immediately if the device is already ready.
  });

  var deviceInformation = ionic.Platform.device();

  var isWebView = ionic.Platform.isWebView();
  var isIPad = ionic.Platform.isIPad();
  var isIOS = ionic.Platform.isIOS();
  var isAndroid = ionic.Platform.isAndroid();
  var isWindowsPhone = ionic.Platform.isWindowsPhone();

  var currentPlatform = ionic.Platform.platform();
  var currentPlatformVersion = ionic.Platform.version();

  ionic.Platform.exitApp(); // stops the app
});
