Difference between content_main.xml and activity_main.xml?

Question

I am new to Android App development. I have Android Studio 1.4. In my layout folder I have two XML files (content_main.xml and activity_main.xml).

Answer 1

Android Studio 1.4 gives a default new option of content_main.xml in the activity. actually activity load the xml file of activity_main.xml for your layout. content_main.xml is the part of main.xml. you can use both for layout,but main.xml is necessary for your Activity. its a option to choose the content_main.xml for design of layout. Hope you get it.
