title: Sending email via Intent.createChooser. Works but returns to different Activity
body: <p>I have and app which requires sending emails with attachments.
  This app contains many activities. Within one activity, I send an email using the following intent:
  startActivityForResult(Intent.createChooser(emailIntent, "Email"), EMAIL_REQUEST);</p>
  
  <p>This works fine. The email is sent.
  (note: onActivityResult is never called. I can live with this, it's not important)</p>
  
  <p>The problem:</p>
  
  <p>After email is sent, the app loads/goes to the startup/initial activity, not the activity from which the email was sent.</p>
  
  <p>How can I return to the activity which sent the email?</p>
  
  <p>Some observations:
  I added some Toast(s) to the onRestart, onPause, and onCreate methods of the startup/initial activity. After the email is sent, the startup activity is displayed but none of the events are called.</p>
