title: How many activities is recommended for keeping in stack?
body: <p>I know how activity lifecycle works.
  But i have one question. How many activities it is recommended to keeping in stack? Example i have about 6 activities. User will be navigate from first activity till the last one. The activities will go step by step from start activity till last one, and with backPress in first one again.
  Here is my mapView<a href="https://i.stack.imgur.com/MGWrm.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/MGWrm.jpg" alt="enter image description here"></a></p>
  
  <p>There is only one step that i'm going from activity 3 to Activity 1.
  In this case i'm using </p>
  
  <pre><code>finishAffinity();
  </code></pre>
  
  <p>for be sure that all stack is clean, and then i'm starting a new one Activity 1 again</p>
