Go back to Previous Application (not Activity) in Android

Question

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

steps:

1. start App1 from Android desk. -->

2. start startActivity(intent) or startActivityForResult(intent,0) to App2 from App1. -->

3. start startActivity(intent) or startActivityForResult(intent,0) again to App1 from App2. -->

4. start ( ? ) to go back to app1(activity) or App2.

I woud like make a dialog to let user to choice back to App1 or App2 in step 4. Is it possible to complete it ?

I have had tried the article here and it just back to the activity on App1 only.

Thanks for any suggestion !

Answer 1

You should override onActivityResults of the activity in App1, and if the user chooses App2, simply call finish on the activity.
