getActivity() where it is defined?

Question

I\'m very new to android and I\'m following this example.

The code says we need to do these steps to get an dialog box:

AlertDialog.Builder builder =         


        

Answer 1

getActivity when you use then no need to put new... such as

PendingIntent pi=new PendingIntent.getActivity(this,0,intent,0); //is wrong

user it as :

PendingIntent pi=PendingIntent.getActivity(this,0,intent,0); //is Right code

here we remove new that provide new allocation but here it provide its allocation via getActivity in with in Activity(this).
