Return to previous application (no activity) in Android

Question

There are two Android applications that call each other: App1, App2.

:

• launch App1 from your desktop PC. →

• run startActivity (intent) or startActivityForResult (intent, 0) in App2 from App1. →

• run startActivity (intent) or startActivityForResult (target, 0) again in App1 from App2. →

• run (?) to return to app1 (activity) or to App2.

I would like to make a dialog to allow the user to select back in App1 or App2 in step 4. Can I complete it?

I tried the article here and it just returned to activity only in App1.

Thanks for any suggestion!

Answer 1

You must override the onActivityResults activity in App1, and if the user selects App2, just call finish on that activity.
