Android: how to call a method after returning from another activity via home button?

Question

Android

The situation is this.
There is an android application with an ActionBar
. From the main activity, we call another activity using the standard code.

Intent intent = new Intent(this, <class>.class);
startActivity(intent);

You can return from another activity either with the Back button or through the Home button on the ActionBar.
You need to call the class method of the main activity, after returning to it through the Home button on the ActionBar.
As a last resort, you can simply make the Home button work like the Back button, because in both cases you need to call the same method.

Answer 1

startActivityForResult()

Answer 2

I love it when people ask and answer themselves. Thank you.
