title: How to reopen a stack of Activities?
body: <p>my App is Launched by "Main.java" (Activity) and opens a Notification and a second Activity called "Sub.java", now I press the Home-Button and the App disapears (everything okay until here).</p>
  
  <p>If I'll now click on the Notification the "Main.java"-Activity is launched, the "Sub.java" seems to be lost.
  Is there any posibility to reorder the Stack of Activities to the front?</p>
  
  <p>Thanks a lot for any answer.</p>
