Android how to show notification on screen

Question

I've been working on push notifications and I am able to implement it and display it on status bar, the problem I am facing is that I want to display it even if the phone is lock, Under the lock screen where it says ("drag to unlock"), I have seen notifications like that but cant find any example to that.

Example: Just like when you received a missed call , it will show it under the lock button on your screen.

Code:

String ns = Context.NOTIFICATION_SERVICE; NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns); int icon = R.drawable.icon_launcher; CharSequence tickerText = "MyApplication"; long when = System.currentTimeMillis(); Notification notification = new Notification(icon, tickerText, when); notification.defaults |= Notification.DEFAULT_SOUND|Notification.DEFAULT_VIBRATE|Notification.DEFAULT_LIGHTS;; CharSequence contentTitle = this.title; CharSequence contentText = this.message; Intent notificationIntent = new Intent(this, MainActivity.class); PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent); mNotificationManager.notify(NOTICE_ID, notification);

Create Notification using NotificationCompat.Builder

NotificationCompat.Builder mBuilder =   new NotificationCompat.Builder(this)             .setSmallIcon(R.drawable.ic_launcher) // notification icon             .setContentTitle("Notification!") // title for notification             .setContentText("Hello word") // message for notification             .setAutoCancel(true); // clear notification after click Intent intent = new Intent(this, MainActivity.class); PendingIntent pi = PendingIntent.getActivity(this,0,intent,Intent.FLAG_ACTIVITY_NEW_TASK); mBuilder.setContentIntent(pi); NotificationManager mNotificationManager =                     (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); mNotificationManager.notify(0, mBuilder.build());

Create Notification using NotificationCompat.Builder but make sure to put visibility to public like

NotificationCompat.Builder builder = new NotificationCompat.Builder(this);         builder         .setContentTitle("Title")         .setContentText("content")         .setSmallIcon(R.mipmap.ic_launcher)         .setVisibility(NotificationCompat.VISIBILITY_PUBLIC);//to show content in lock screen
