title: Why there isn't a simpler way to stop an activity from another?
body: <p>I know there are many topics about this, and I understand (or at least I think I do) the Activity lifecycle. I know the Activity itself should handle its lifecycle, including the process of stopping the Activity.</p>
  
  <p>But, in some cases, this is just not practical, for example, if you have a controller, to manage your interface, and maybe receiving I/O results.</p>
  
  <p>So, wouldn't be nice just to send some Intent with an action like a <code>ACTION_STOP_REQUEST</code>, and let the Activity handle it?</p>
