title: Side effects of activity no longer visible?
body: <p>I wrote a simple app reading a page of text via text-to-speech. It works in principle but now I need to implement onPause(), onResume() etc. in a way that would make sense to the end user.</p>
  
  <p>Specifically about onPause() I have 2 options:</p>
  
  <ol>
  <li>Pause reading, with the intent to
  continue exactly from point left.</li>
  <li>Continue normally, as if the
  activity is still visible.</li>
  </ol>
  
  <p>The 2nd option looks more sensible because if it's not a visual activity, why let visual disturbances interrupt speech?</p>
  
  <p>However, I am not sure whether there are other system-wide considerations ("side-effects") that I must be taking into account when implementing onPause() as a "do nothing" function.</p>
  
  <p>Aside from onPause() being called when an activity is no longer visible, are there other events or side-effect that I should take into consideration when deciding whether to stop or not to stop text-to-speech?</p>
