Cant understand isFinishing

Question

I am learning Google IO 2012 code
In one of the actions (HomeActivity.java) they do the following:

void onCreate(Bundle savedInstance) { if(someCondition) { // start some other activity here finish(); // finish this activity } if(isFinishing()) return; // More code here } 

I wonder why they do not put return immediately after finish() , but instead checking isFinishing() ?

Answer 1

Activity can be completed in several ways.

finishActivity from the action that called startActivityForResult

finishAffinity and finishFromChild

So isfinishing used to account for such cases.
