Go back to Previous Application (not Activity) in Android
<p>There are two Android applications calling each other: App1, App2.</p>

<p>steps: </p>

<ol>
<li><p>start App1 from Android desk. --> </p></li>
<li><p>start startActivity(intent) or startActivityForResult(intent,0) to App2 from App1. --></p></li>
<li><p>start startActivity(intent) or startActivityForResult(intent,0) again to App1 from App2. --></p></li>
<li><p>start  ( ? )  to go back to app1(activity) or App2.  </p></li>
</ol>

<p>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 ? </p>

<p>I have had tried the <a href="http://stackoverflow.com/questions/4038479/android-go-back-to-previous-activity">article here</a> and it just back to the activity on App1 only.</p>

<p>Thanks for any suggestion !</p>
