native notification android code in cordova plugin java class

I'm some what aware of cordova and now I'm implementing a notification in my plugin class.

I have used the below android code to create the notification in my java class. I have imported all the packages related to notification. But i'm getting the notification exception and unable to get the notification

NotificationManager notificationManager = (NotificationManager)this.getSystemService(getApplicationContext().NOTIFICATION_SERVICE);
    Notification notification=new Notification.Builder(getApplicationContext())
    .setWhen(System.currentTimeMillis())
    .setContentTitle("Welcome")
    .setTicker("Click here to see the offers...")
    .setContentText("Click here to see the offers...")
    //.setSmallIcon(1)
    .setAutoCancel(true)
    .build();

    notificationManager.notify(info, notification);

And the exception I'm getting is

NotificationService(802): Not posting notification with icon==0:     Notification(pri=0 icon=0 contentView=com.ionicframework.dummy292686/0x1090085 vibrate=null sound=null defaults=0x0 flags=0x10 when=1439564895752 ledARGB=0x0 contentIntent=N deleteIntent=N contentTitle=7 contentText=31 originalPackageName=N originalUserId=0 tickerText=31 kind=[null])

Can some body give suggestions to write the notification logic in a cordova plugin java class?
