How to change title of Activity in Android?

Question

I am using

Window w = getWindow();
w.setTitle(\"My title\");

to change title of my current Activity but it does not seem to work.

If you want it one time & let system handle the rest (not dynamic) then do like this in your manifest file:

         //This is my custom title name on activity. <- The question is about this one.
             //This is my custom Icon title name (launcher name that you see in android apps/homescreen)
