title: starting multiple activities in chain
body: <p>Hello android developers</p>
  
  <p>I have three Activities, which are started in some kind of chain. </p>
  
  <p>Activity A -> has start button,which starts Activity B.</p>
  
  <p>Activity B -> 
  cancel button,which returns back to Activity A. 
  And capture button,which starts activity C with some data.</p>
  
  <p>Activity C ->
  retake button,which returns back to  Activity B
  use,which must resume activity A with some data.</p>
  
  <p>My question is which is correct way to start these activities in chain,and how can I maintain flow from Activity C to A.</p>
