Re: [android-developers] parcelable again: passing object BACK through activity stack

Yes, a lot :)

Try out your code using 'hasPushedActivityB' and then rotate your phone or, if it has a physical keyboard, slide out the keyboard: 

The activities will be recreated and your 'hasPushedActivityB' of the new activity A will be false, but the new Activity B will be showing.

Not sure how to try this out on the emulator.

 

Just use onActivityResult.:)

OK, but one more thing is not clear from the documentation at http://developer.android.com/reference/android/app/Activity.html
under "Starting Activities and Getting Results" which states: "When an activity exits, it can call setResult(int) to return data back to its parent."
Since the Intent is returned to the parent activity inside onActivityResult, what is the difference in using setResult and using putExtra in Activtity B
on the Intent to pass back a custom result parameter to Activity A?

(There is an example here: http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/SendResult.html
and then there is the NotesList application.)

Thanks,
