Since many months, as an Android developer, I use the Activity-Fragment template to implement Activity. But it looks like Google decided to change the template (again).
A few days ago I upgraded Android Studio to version v1.4 beta 4. I noticed a new template for creating activity. When I tried to create a new activity from new-> Activity, I could not find "New activity with an empty fragment." Instead, two new options have appeared: "Empty Activity" and "Blank Activity". 
I selected Blank Activity and added the following files.
- MainActivity.java (activity class)
- activity_main.xml (activity layout)
- content_main.xml (activity content included by activtiy_main.xml)
So my question is: what is the new development pattern that an Android developer should follow?
---- EDIT ---- How to use the previous Activity-Fragment template In order to return the "Fragment" to the image, you need to select "use fragment" in the dialog box that appears after selecting "Empty action",
