A:

Use startActivityForResult() instead of startActivity() and override onActivityResult() in Screen A
Pass item index along with the other data to Screen B 
Once modified in Screen B - Send all the data back along with the index, back to Screen A via a Bundle (use setResult() before finishing the Activity in Screen B).
Once you finish Screen B, you'd get a call back in onActivityResult(), where you can extract the data and update your list. 
After updating the data in your list, don't forget to call ListAdapter.notifyDataSetChanged();
Please note, Since you use static list, you have to pass data back-and-forth

 Q:

How should i decode this data/these strings

I am currently trying to work through an OLD python CTF challenge, the script of the server is provided, and the idea is to send the correct data to this server,

 A: 

 practice startActivityForResult () alternatively of startActivity () and override onActivityResult () in Screen A 
 Pass item exponent along with the other datum to Screen B 
 Once modified in Screen B - Send all the datum back along with the index, back to Screen A via a Bundle (use setResult () before finishing the Activity in Screen B). 
 Once you complete Screen B, you'd get a call back in onActivityResult (), where you can excerpt the data and update your list. 
 After update the datum in your list, don't forget to call ListAdapter.notifyDataSetChanged (); 
 Please notice, Since you use inactive tilt, you have to pass data back - and - forth
