How to check if an activity is continuing

Question

In my app, I am trying to run multiple photos through a photo editor (one at a time). I have it set up in a for-loop at the moment, but I feel like it is overloading the photo editor and not actually waiting until the current edit session is over, so I wanted to put a control statement in my for-loop to check if the session was still active.

Is this possible?

Answer 1

Easier to tell when the current is over than polling to see if it is still active. If you start it with startActivityForResult, your calling activity will be notified when the invoked activity ends.

Have a look at Starting Activities and Getting Results in the Activity docs for an example.
