How to make a Facebook Messenger-like notification like this in Android

I want to implement notifications like the one in the following image.

Notification appears any time. I think it's of course a background service waiting for new messages from the server then shows this. What I think this is an activity implemented as dialog with this custom UI. Am I correct? And is it a normal startActivity method from the service? And how do I do the transition animation to make it appears slowly from left to right with zooming when show up?

Enter image description here

Check out this link He provides information about how to add them on your screen.

The trick is to add a View to the WindowManager like following code

private WindowManager windowManager;
private ImageView chatHead;

public void addView()
  windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);

  chatHead = new ImageView(this);

  WindowManager.LayoutParams params = new WindowManager.LayoutParams(

  params.gravity = Gravity.TOP | Gravity.LEFT;
  params.x = 0;
  params.y = 100;

  windowManager.addView(chatHead, params);

Don't forget to add the permission <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
