In ConfirmOrder Activity you are creating a new empty intent by doing this.

Intent intent1=new Intent();

So definitely intent1.getStringArrayListExtra("selectedItems"); this will return null because nothing is find with selectedItems String inside intent1. You have to call getIntent(String uri) method of Intent class to get the values putted in your first Activity.

Use:

Intent intent1=this.getIntent();
intent1.getStringArrayListExtra("selectedItems");

Note:

public static Intent   getIntent  (String uri)

This method was deprecated in API level 4. Use parseUri(String, int) instead.

use

 Intent intent1=this.getIntent();

instead of

 Intent intent1=new Intent();

for getting value in next Activity
