Question

Well, I was wondering whether I could load different views from same application for different android versions. I thought that I could create an activity that can call one of the two separate activities defined for different versions of android via intent. I mean suppose that in one activity I have used action bar which is available from ice cream sandwich only, and other could possibly to use views in earlier android releases.

Answer 1

1) For layout that support multiple screens you can refer this

2) If you want to load different layout depending on different android version then you can create different layout xml files and then in the activity, for example below code

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.GINGERBREAD) {
     // only for android older than gingerbread
     //call setContentView with your layout
}

3) You can have layout in layout-v(version-number) folder inside your res folder. Where for example for SDK 11 the folder name will be layout-v11
