Ionic Local notification, not able to access

I have implemented Local Notification Code but not able to access it through android emulator or physical device .


Controller

constructor(public navCtrl: NavController, public navParams: NavParams,
    private localNotifications : LocalNotifications,private plt : Platform,
    private alertCtrl:AlertController) {
    this.alarmsList = 'breathe';
    this.plt.ready().then((rdy)=>{
      this.localNotifications.on('click',(notification,state)=>{
        let json = JSON.parse(notification.data);
        let alert=this.alertCtrl.create({
          title:notification.title,
          subTitle:json.mydata
        });
      });
    });
  }

 example(){
    this.localNotifications.schedule({
      id:1,
      title:'Attention',
      text:'Saurabh Notification',
      at:new Date(new Date().getTime() + 1 * 1000),
      data :{mydata:'hidden msg'}
    });

View

<ion-list *ngSwitchCase="'breathe'" class="list-alarms">
      <div class="list-header-custom breathe-time" text-uppercase text-center>
        TEXT
        <ion-fab bottom right edge>
          <button ion-fab mini color="light" (click)="example()"><ion-icon name="add"></ion-icon></button>
        </ion-fab>
      </div>

Are you getting any errors?

No i am not getting any error on Android device .
In browser its says > include cordova.js

Does it show in the list of you use this.localNotifications.getAllScheduled()? (Returns a Promise)

What happens when you run the command? Paste the console output
